Re: [Python-Dev] Re: anonymous blocks (off topic: match)

 PS. a side effect of the for-in pattern is that I'm beginning to feel that 
 Python
 might need a nice switch statement based on dictionary lookups, so I can
 replace multiple callbacks with a single loop body, without writing too many
 if/elif clauses.

That's funny.  I keep wondering if match from the ML world would
make sense in Python.  I keep thinking it'd be a really nice thing to
have.

 PEP 275 anyone ? (http://www.python.org/peps/pep-0275.html)
 
 My use case for switch is that of a parser switching on tokens.
 
 mxTextTools applications would greatly benefit from being able
 to branch on tokens quickly. Currently, there's only callbacks,
 dict-to-method branching or long if-elif-elif-...-elif-else.

I think match from Ocaml would be a much nicer addition to Python
than switch from C.
