So how do I do an efficient:
class A {
array b;
};
A c=A();
...
then from with the CMOD:
c->b+=({12});
I would like the += code to destructively expand array b, which would be
possible if it had only one reference.
But object_index_no_free adds a reference, you say. So how do I solve
this?
I use this:
push_int(12);
f_aggregate(1);
Pike_sp++;
object_index_no_free2(Pike_sp-1, portal,0, MK_STRING_SVALUE("_datarows"));
stack_swap();
f_add(2);
object_set_index2(portal,0, MK_STRING_SVALUE("_datarows"), Pike_sp-1);
Pike_sp--;
I realise that I need to run pop_stack() at the end instead, but that
still leaves me puzzled about the efficient append.
