So if one is interfacing with a system that uses call-backs, any target
of a call-back can only appear in the main procedure if the relevant
'type xxx is access procedure yyy' also appears in the main procedure?

So even with a wonderful set of bindings done as library routines to
handle all the details, the minimum Windows program requires the user
to write a main procedure (which may be trivial) and a separate package
that does the work.
