For me, too. But note that we should keep does the ultimate

Do we need to consider boxed vs un-boxed, E.G. Int vs int?

For designing, we need to consider
- every way you might *want* to write two different signatures
- every kind of transformation or differing case in how binding works
That falls under the first item. Put it on the whiteboard.
multi sub call_OS_prim (int) # low-level interface code, written in
C and imported.
multi sub call_OS_prim (Int) # wrapper that checks for undef first,
etc.
#then calls the first one. Written in Perl in the module.
