__traits(compiles, cast(T) o) is true even if the cast blows up in CTFE, so
that doesn't work.
This works fine at runtime, but explodes in CTFE:
---
bool isInstanceOf(T, O)(O o) {
return (cast(T) o) !is null;
}
---
CTFE doesn't like "!is null" ("cannot compare [...] at compile time").
Moreover, in CTFE a failed cast terminates the interpretation ("cannot
