Martin v. Löwis added the comment:
Two observations:
1. This issue is only about identifiers. So processing of string literals is
technically out of scope.
2. I'd suggest to replace .translate with regular expressions:
py> re.sub('[^(){}\[\]]','','foo(b[a]{r}≠)')
'([]{})'
I'm sure people interested in performance will want to time this approach.
