I always do the cast, though honestly, I think that character literals should
default to dchar rather than char. I'm not sure that we could ever talk Walter
into that though, particularly if he thought that doing so would break code
(I'm not sure whether it would or not, but using char for a character is
almost always a bad idea, so defaulting to char for character literals just
doesn't make sense to me).
I'm not aware of there being a shorter way to get character literal to be
dchar, though I suppose that if you had to do it a lot, you could create a
function with a short name. e.g.
dchar toDC(dchar d)
{
return d;
}
and end up with
toDC('a')
instead of
cast(dchar)'a';
but I'd probably just use the cast. It certainly sounds like a nice
enhancement though to be able to do
'a'd
especially if the c and w versions gave errors when the character wouldn't fit
in a char or wchar, which isn't the case with a cast.
