It's a generic subprogram parameter.  In the instantiation of the generic,
an actual subprogram is specified for "=" (in this case), and then every
occurence of the generic "=" in the generic is replaced by the actual "=" in
the program unit created by the instantiation.

The generic is letting the instantiator determine how to do "=".
