I feel the same about writing. But you have to consider how code
is read, too. C# kind of has an infix cast operator: You write `x
as TargetType` there. In D, you can do the same:
auto ref TargetType as(TargetType, SourceType)(auto ref
return cast(TargetType) object;
auto result = fun(x.as!int).as!string;
I'll agree that an operator would look nicer, but – as is more
often than not the case with D – if a library solution is found
that isn't horrible, the probability that the language will be
extended is around 0.
