-# ki roadmap
-
-## 0.2.0 Make it a viable language
-
-* **DONE** enclose every ki call in (function() {})(), if this doesn't break hygiene tricks
-* **DONE** allow property access without (js ), e.g. (bar.dostuff 1 this.props) instead of
- ((js bar.dostuff) 1 (js this.props))
-* **DONE** implement ki require to make it practical to use node modules
-* **DONE** if when
-* **DONE** cond
-* **DONE** and or
-* **DONE** not
-* **DONE** eq neq
-* **DONE** letv
-* **DONE** do
-* **DONE** def defn
-* **DONE** nil
-* **DONE** define truthiness (in line with ClojureScript and Mori)
-* **DONE** ns: every ki () form should introduce a namespace, either anonymous
- (no ns form) or named, ki (ns foobar (def ...))
- Every def (and defn) should define a var as well as place the value in
- the _ki object, so that it can be used/interned in other ki blocks with different
- namespaces (or other ki blocks with the same namespace).
-* **DONE** fully qualified identifiers foo/bar
-* **DONE** use: intern all functions of a module (TODO: warn on aliasing)
-* **DONE** support js object creation with js new, or just decide to leave it as
- (js new Date) I like this option better (we should document it and that's it)
-* **DONE** data literals
-* **DONE** loop, recur, while
-* **DONE** multiple arities
-* **DONE** threading macros
-* **DONE** chaining, doto
-* **DONE** add sub mul div mod
-* **DONE** lt gt leq geq
-* **DONE** letc (backcalls style continuations)
-* **DONE** apply
-* **DONE** bind
-* **DONE** keywords **NOTE** keywords do not evaluate to themselves and do not extract values from collections. We could add a reader macro for this (**TODO**).
-* **DONE** multimethods
-* **DONE** atoms
-* **DONE** exceptions
-* **DONE** allow generated scripts to run in browser (avoid require)
-* **DONE** fnth (fn bound to this)
-* **DONE** be consistent in binding to this
-
-* **DONE** testing
-
-* example with node
-* **DONE** example with React
-
-## 0.3.0 Add the nice to have
-
-* destructuring
-* multiline strings
-* consider integrating cspjs
-* CPS modeled after tame.js
- In tame we would have something like
- (await (setTimeout (defer) 100))
- (prn "Hello!")
- which would require exploring the AST. It could become something like
- (with_defers [a]
- (await (setTimeout a 100))
- (prn "Hello!"))
- or even more explicitly
- (with_defers [a]
- (await a (setTimeout a 100))
- (prn "Hello!"))
- which could also be used as
- (with_defers [a]
- (setTimeout a 100)
- (await a)
- (prn "Hello!"))
- Or just limit defers to last argument as in letc. The advantage over letc is
- easier parallelism of e.g. multiple requests to server.
-* named parameters and defaults
-* optional arguments to functions (catpured in a vector)
-* regular expressions
-* implement a REPL
-* additional functions/forms
- * condp case
- * for (comprehension)
-* "application/ki" script type and in-browser expansion (browserify?)
-* create something like http://kanaka.github.io/clojurescript/web/synonym.html
-
-## 0.4.0 Make it a real lisp
-
-* implement macros in pure ki
- Workflow: ki script reads the input file, identifies forms with ki macro foo,
- or (defmacro foo ...) inside ki forms (we'll have to choose), builds a string
- of code to execute in ki (i.e. complied through sweet.js as a library and
- executed in node), that defines macros as functions and calls a macroexpand
- function that takes in input the input file and returns a string in which all
- invocations of (foo ...) are replaced with their expanded version.
- The result is then compiled in sweet.js and written in output.
-* have a ki script replace the sjs script for handling the double pass
- Also informative: https://github.com/swannodette/hello-cljsc/blob/master/src/hello-cljsc/core.clj
-* browserify the ki script
-* make LightTable plugin
-
-## 0.5.0 Add support for libraries
-
-### Browser
-
-* React.js
-* jQuery
-* D3
-* KnockoutJS
-
-### Node
-
-* Plain node
-* Express

+ // rewrite of the resolveCtx function than with the while loop
+ // optimization - https://gist.github.com/srikumarks/9847260 - where the
+ // recursive steps always operate on a different context.
+ //
+ // This might make it seem that the resolution results can be stored on
+ // the context object itself, but that would not work in general
+ // because multiple resolve() calls will walk over each other's cache
+ // results, which fails tests. So the memoization uses only a context's
