The variable-sized proposal just allocates differently (non-resizable) PMCs. Same thing as we are already allocating differently sized GC-able items (PObjs) namely: PMC, Buffer, String, and Buffer-like.

The cstruct is describing the internals of a PMC (which happen to consist of C structure items) leo
