Feature or enhancement

Right now it is:

>>> ft'a'
  File "<python-input-3>", line 1
    ft'a'
      ^^^
SyntaxError: invalid syntax

I propose:

>>> ft'a'
  File "<python-input-3>", line 1
    ft'a'
      ^^^
SyntaxError: can't use both "f" and "t" prefixes for strings at the same time

cc @lysnikolaou

More tersely, "f" and "t" prefixes are incompatible.
