What invocant is constructed in this signature then?
    method foo ($just_a_named_param)
Is the signature for &foo really the same as that of bar?

       sub bar ($just_a_named_param)

As Larry said, they shouldn't be the same; the first one is

    &foo.signature === :($ : $just_a_named_param);

The second one is:

    &bar.signature === :($just_a_named_param);

I was sort of assuming you could tell by a signature if it was for a
method or a sub.

That's correct; the "method" keyword augments the signature with an  
unnamed
"$" invocant if it's not explicitly specified. (In Pugs.Val.Code  
terms, that's nullID for
both the p_label slot and (v_name . p_variable).)
