Not really.  First, because such "type information" is often encoded in
the parameter name itself -- "count" is (or should) always be an int,
and I don't need a type declaration to tell me that.  And then you have
doctest (http://www.python.org/doc/lib/module-doctest.html) which is the
best thing since sliced bread.  (Really!)

But more importantly, leaving out type declarations is only a small part
of what makes dynamic languages so productive:
