>>how do you accurately hint to linters, in a language that encourages duck typing, the type a method parameter is likely to take?

You didn't check the Method::Signatures link or do I misunderstand your position?

Also check Moose@CPAN, which have typing of object attributes. It isn't like a fully typed language, but it should help a lot.

Edit: Link discussing type checking of attributes in Perl. Should be possible to have something similar in other dynamic languages? http://search.cpan.org/~doy/Moose-2.0602/lib/Moose/Util/Type...

Edit: Please check the links and see if Perl solves your problems? I am curious. (-: Writing a PEP to get something similar into Python is optional. :-)

I didn't look, tbh. Python 3 already has type annotations, but what interests me if how do you nail down types whilst preserving duck typing, or dealing with a method that is already passed duck typed objects.

I'm not going to copy/paste the content/source from links I've given. :-)

(There are easy-to-read abstracts/"synopsis" at the start of both pages.)
