My intention was that there should be a "static" declaration to be used
with parameterized modules; something like:
baz(A,B) -> ...
where baz/2 would not get any automatic hidden variable, so you could
call foo:baz(X,Y) directly without creating an instance of foo first. I
just never got time to add this. If parameterized modules become a
full-fledged language feature, some form of static-declarations should
definitely be part of that.
For anyone wondering why nothing is happening with this stuff, it's just
a question of time and priorities. I'm not working for Ericsson, I have
very little spare time these days, and the OTP team have lots of other
higher prioritized things to do.
