Sure, it's not complicated. It's something I had done in this
other code and
showing for example.
Yeah, see I don't feel making a simple thing like an array into
something more complex by wrapping it in templates is ever a
good
thing to do.
I just think it's a missed opportunity that the compiler doesn't
support any of this in the language.
It would appear at face value to be a great opportunity for
lowering.
Assignment can lower to .copy(), operators can lower to
map!(...)
I can tell you, if I tried to explain to my colleagues that we
should
wrap an array in a template so assignment works, they would
laugh at
me, then ridicule me, and then they would dismiss D. Better to
say
it's not supported than to show them that approach.
Yeah, it is an excessive solution. I guess just wanted to talk
about my thing and didn't think it through. I think laughing at
and ridiculing are the same thing though. Anyway, lowering to
copy built-in to the language, at least, would be pretty great.
Especially if it worked like foreach and picked up local symbols,
so that custom copy and map implementations could be used
wherever they were defined.
