isRangeOf ?

[bearophile via Digitalmars-d-learn]

Sometimes I have a function that needs an iterable:

void foo(Range)(Range data)
if (isForwardRange!Range && is(Unqual!(ForeachType!Range) == 
int)) {}


So is it a good idea to add a "isRangeOf" template to Phobos?

void foo(Range)(Range data)
if (isRangeOf!(Range, int)) {}
