The inspect module has no function isgenerator.

Is this wanted at all ?
After checking
http://www.python.org/dev/summary/2006-06-01_2006年06月15日/#inspect-isgenerator
that points to:

it seems a patch for this function would not be accepted.

I know two real usages:
- the nose and py.test packages accept a generator function, as
described here:
http://codespeak.net/py/dist/test.html#generative-tests-yielding-more-tests
http://somethingaboutorange.com/mrl/projects/nose/#test-generators.
functions are collected with the help of the "inspect" module.
- the twisted framework use "inlineCallbacks": a function executes an
asynchronous operation and yields; execution is resumed when the
operation gets its results. "inlineCallbacks" is actually a a decorator.
Both cases make the difference between a generator function and a
regular function, even if it returns a generator. And they don't want to
execute the function to know it...

Maybe there should be two new functions then ? isgeneratorfunction and 
isgenerator.

I'm attaching a patch, it adds two new functions and removes some
constants defined in the code that can be retrieved from compiler.consts

Adding a patch that fixes inspect test and doc.

I merged my working copy with your patches and they look fine. I fixed a
typo on the method doc ("is" instead of "i") so I'm attaching my
inspect.py.diff patch

Sorry, I attached the wrong file
The previous post saying "fixing typo" should attached inspect.py.diff.
This is the one.

My dear, what is wrong with my browser (or with me). Now, yes, the one
with the typo.

And now I'm attaching a new patch test_inspect.py.diff with a more
complete test coverage. You didn't add isgenerator nor
isgeneratorfunction tests. I did.

Fixed in r60884. Thank you all very much!
