I got bit by this quite recently, leaving out a comma in a long list of strings and I only found the bug by accident.
This being python "ideas" I'll throw one out.
Add another prefix character to strings:
a = [m'abc' 'def'] # equivalent to ['abcdef']
As MRAB suggested, a prefix for a compile time dedent would likely be more useful - then you'd just use a triple quoted string and be done with it. The other one I occasionally wish for is a compile time equivalent of str.split (if we had that, we likely wouldn't see APIs like collections.namedtuple and enum.Enum accepting space separated strings). Amongst my ideas-so-farfetched-I-never-even-wrote-them-up (which is saying something, given some of the ideas I *have* written up) is a notation like: !processor!"STRING LITERAL" Where the compile time string processors had to be registered through an appropriate API (probably in the sys module). Then you would just define preprocessors like "merge" or "dedent" or "split" or "sh" of "format" and get the appropriate compile time raw string->AST translation. So for this use case, you would do: a = [!merge!"""\ abc def""" Cheers, Nick. -- Nick Coghlan | ncoghlan@gmail.com | Brisbane, Australia
