That's initialization, not assignment, which is subtly
different. It will call the postblit on aaa instead of
opAssign. A postblit can be defined this way:
this(this)
{
}
There is no way to access the original a from the postblit. All
fields have already been copied, you can use it to duplicate
reference types, increment reference counts, and other things
like that.
Wow, that's great! Thanks for the clarification you two!
