An explanation would be more helpful.
For many years is(xxx) been reviled as the ugliest thing in the
language. The simple forms are OK, but features kept getting piled onto
it until it became clearly unworkable.
So why not keep the simple forms and just replace the more obscure
functionality that is better expressed by other means?
Removing is expressions entirely would break most D code (at least it
would break all of mine).
And there are stupidities like:
alias void delegate () dg;
alias void function () fn;
static assert(is (dg == delegate)); // true
static assert(is (fn == function)); // fails!
I'd like to just see that fixed, but then old code would be silently
miscompiled...
