in PIR you can override (or implement) a vtable method using the :vtable
flag.
before that, in the past, this was done by prefixing the vtable name with 2
underscores.
While ack'ing for ".constant" (to be replaced with .macro_const), I found
that the following file defines constants for all entries:
runtime/parrot/include/vtable_methods.pasm
for instance:
9:.constant PARROT_VTABLE_ADD_INT_METHNAME "__add_int"
2 questions arise:
1. is the double__underscore thing still supposed to work and if so, is it
deprecated?
double__underscore still the only way to overload a non-vtable method,
for example, the opcode add (with MMD) :
.namespace [ 'MyInteger' ]
.sub 'set_integer_native' :vtable :method
.param int val
...
.end
.sub '__add' :multi(MyInteger, MyInteger) :method
.param pmc val
.param pmc dest
...
.end
François.
2. are the .constant definitions still needed? i.o.w., does updating that
file make sense or can i save myself that trouble.
thanks,
