Hi,

Many times I have encountered a problem with wrongly spelled named arguments being interpreted as position arguments. Especially when the casing/spelling of arguments change (are changed by colleagues). Here is an example:

*** Test Cases ***
TC
    KW
    KW  named1=1
    KW  named_1=1
    KW  Named2=1

*** Keywords ***
KW
    [Arguments]    ${named1}=1  ${named2}=2
    Log To Console    ${\n}Got named1: "${named1}"
    Log To Console    Got named2: "${named2}"

And the output below. Problematic are the last and second to last case.

Got named1: "1"
Got named2: "2"

Got named1: "1"
Got named2: "2"

Got named1: "named_1=1"
Got named2: "2"

Got named1: "Named2=1"
Got named2: "2"

I propose the following solution: Log/print a warning if

• a positional argument contains a "=", and
• the part that is left of the "=" symbol is similar to the name of a named argument.

Similarity could be determined, for example, using simplified/modified levenshtein distance.

I think this is the location where such a check could be implemented, although I'm not sure whether warnings can be logged by this class (using import warnings?):
