Hi,
I have designed a class based system that involves
self-delegation instead of override.
It is similar to event based programming.
I have defined an event as a container type that holds
functions(or possibly delegates, but the desire is to avoid them).
class Base
{
alias
I should point out that the code still doesn't work. It simply
doesn't crash. It seems to jump to another code location that
fails silently. I might not be fixing up the stack frame
correctly or or doing something D expects. Hard to no because
when I try to step over the `call` instruction it
2. C++ defaults to dword ptr, D to word ptr. Copying and
pasting the code results in hard to find bugs.
It would seem to me that that D should default to the pointer
size for indirect accessing when pushing and popping.
push [3]
should push a size of void*.sizeof.
