With list comprehensions and generators becoming so integral, I'm not sure about "unpythonic". And a syntax just occured to me -- what about this: [y*x for x,y] ? (that is: [<expression> for <argument list>] It's just like the beginning of a list comprehension or generator, but without the iterator. That implies that one must be given, and the result is therefore a callable object. Wouldn't do anything more or less than present day "lambda", but gets rid of the weird keyword, and integrates nicely with list comps and generators. It's currently a syntax error, and it requires no special delimiter -- it's really just an extension of list comp syntax. -- Terry Hancock ( hancock at anansispaceworks.com ) Anansi Spaceworks http://www.anansispaceworks.com -- http://mail.python.org/mailman/listinfo/python-list
