Idle stays confused and will wrongly color the list instance name until
it is changed. Calling the file list 'fnames' or 'filenames' would have
been clearer to both me and Idle.
Correct. The downside of editors that colourise text is that sometimes
they colourise it wrong. In this case, how is the editor supposed to know
that list no longer refers to the built-in list?
This is yet another good argument for being cautious about shadowing
built-ins.
After posting I remembered that there are also colorized text blocks on
web pages. Each person will have to decide for themselves whether the
convenience of reusing a builtin name is worth having their code
mis-colorized. As a reader, I decided that it is not.
