Oh and the workaround I'm using is this:
---
void func(T)(T vals) {
static if(isInputRange!T) {
static if(isIntegral!(ForeachType!T)) {
// Do something with range
}
} else {
// do something with scalar
}
}

which is a bit ugly.
Maybe this could work:
---
enum isSupportedRange(T) = isInputRange!T && is(ForeachType!T)
&& (isIntegral!(ElementType!T));
---
ElementType() should return exactly what you excpeted with
ForeachType().
Yep, that works, thanks!
I also found I can do it with __traits, but I think your way is
cleaner.
enum bool isSupportedRange(T) = __traits(compiles, isInputRange!T
&& isIntegral!(ForeachType!T));
cheers,
