I'll second that!  Coming from a C++ background, there's something that
makes me feel all warm and fuzzy to know that my closures and function
objects can have the exact same syntax as "real" functions.  It makes it
easier to replace a function with a functor during refactoring, for one
thing.  Also it means that down deep within a subroutine I don't have to
think about unimportant details like "this 'foo' is a method, and needs
to be called /this/ way; but 'bar' here is an object, and needs to be
called /that/ way" - I know that they are both callable, and so can just
use the same syntax on both.  I think people from a Python background
would like this as well, since Python has the option to overload () too.
