The current VMMaker for SqueakVM does not use or support pragmas
(method annotations). Converting to pragmas makes VMMaker unloadable
in older Squeak images.
It should be feasible to have the Cog VMMaker handle message send
declarations (although I have not tried), but the reverse may not
be supportable. If that is the case, then plugins that are intended
for use on both SqueakVM and Cog would need to use message-based
declarations, at least until such time as we decide to move SqueakVM
to use method annotations.
Follow-up discussion concerning method annotations in SqueakVM and
Cog VMMaker is probably best moved to the vm-dev list.
