[Python-ideas] ML Style Pattern Matching for Python

[Ian Bicking]

I don't have any real opinion on this, but this old experiment seems related
to the discussion: http://svn.colorstudy.com/home/ianb/recipes/patmatch.py

Yes, it's a bit of fun. This would never get into Python anyway, but I'd
like
it nevertheless. (It is Ocaml's record syntax with some small tweaks.)

It would be possible to realize it though. With "inspect.getfullargspec" you
can see the a function's signature. There might be problems with efficiency,
because you'd have to search through globals and locals repeatedly. You you
could however store which class matched, somewhere in the code object.

Storing this kind of information would go against Python's nature as a
dynamic
language, even though it would work as expected in 99% of the use cases. Oh
well ...
