Method and function declarations with signatures and no source filter

MethodSignatures provides two new keywords, func and method, so that you can write subroutines with signatures instead of having to spell out my $self = shift; my$thing = @_

func is like sub but takes a signature where the prototype would normally go. This takes the place of my$foo, $bar = @_ and does a whole lot more.

method is like func but specifically for making methods. It will automatically provide the invocant as $self by default. No more my $self = shift.

It also allows signatures, very similar to Perl 6 signatures.

It also does type checking, understanding all the types that Moose or Mouse would understand.

And it does all this with no source filters.
