I would like str.replace, when given a set of characters, to replace occurrence of any of the characters in the set. I.e.
'ASDFGH'.replace(set('SFH'), '') == 'ADG' should then hold.
It would mean I would not have to go to the trouble of using the re module for a common string operation.
By extension, a set of multi-character strings should have any occurrences of the strings replaced, (in an indeterminate order, so watch out for replacement sets of strings were one string is a sub-string of another).
