This is actually a good reason to use a module like Params::Validate, it helps provide documentation for a subroutine/method.

For example: 

 sub do_the_thing
 {
     my %p = validate( @_, { foo => { isa => 'Foo::Big' },
                             size => { type => SCALAR, default => 10 },
                             ...
                           } );
     ...
 }

This way all the possible named arguments are documented, as well as their types/classes, defaults, etc. Along with good names, this really does completely document what parameters are accepted, _and_ as a bonus does actual validation on them.
