Agreed, and there are a few string functions that could be extended (to
take a sequence) to handle more cases that push folks to regex, perhaps
earlier than they should.
str.replace come to mind. It's a annoying to have to chain it 5 times
while we could pass optionally a tuple.
That would be handy. Either pass two sequences of equal length
(replace each with the corresponding), or one sequence and one string
(replaceactual any with that). (And yes, I know that a string IS a
sequence.) This would want to be semantically different from chained
calls, in that a single replace([x,y,z], q) would avoid re-replacing;
but for many situations, it'll be functionally identical.
Would it check first-to-last or longest-to-shortest? I think that
longest-to-shortest would be the most useful.
>>> old = ('cat', 'cats')
>>> new = ('mouse', 'mice')

>>> # First-to-last.

'mouses'

'mice'
