‘l’, ‘O’, or ‘I’ names not checked in function parameters

[atzannes]

The following code does not raise any warnings:

def f(l):
    return l

It seems that E741, E742, and E743 do not check function parameter names for bad names, but PEP8 (names to avoid) does not seem to make a special exception for those.

I believe #700 has the rationale for this choice

Actually, it looks like there is some debate about whether to flag function parameters vs arguments at call-sites, but most seem to agree that we should flag function parameters (at function declarations) but not function arguments (at function call-sites). PR #853 seems to implement that logic, but has not been released yet, so I'll wait for the next release of pycodestyle.

@asottile thanks for the helpful pointer.

I'm going to close this issue as it appears to have been resolved by PR #853
