Would a Preelaborate or Pure pragma in the generic package make any
difference here? (although I don't think Preelaborate would be legal
in PragmARC.Reflection)
What do the compilers actually do? My guess is that they all
instantiate the package(s) at compile-time, but I don't know (and I
only have access to GNAT).
