How should the PerlScalar PMC behave in the following situation?
new P0, .PerlScalar
new P1, .PerlArray
assign P0, P1
The assign opcode will call PerlScalar's set_pmc function, which needs
to get a value from P1, so it calls PerlArray's XXXXX function??
The two obvious options seem to be:
vtable method get_scalar(pmc)
vtable method get_value(pmc, context)
I would prefer the latter, because it is less Perl-centric, and keeps the
sizeof the vtable smaller once other contexts are introduced; however,
this is slightly slower, as get_value will need to check its context and act
accordingly. If context was an enumeration, a simple switch statement
would suffice. In this case, it might be interesting to benchmark the
consequences of replacing some of the other get_X vtable functions.
e.g. get_integer(pmc) -> get_value(pmc, CONTEXT_INTEGER)
Comments, anyone?
