Sometimes I have a function that just needs an iterable (sometimes and opApply-based iterable is OK too, but this is enhahcement request is just for ranges):


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


So perhaos it's a good idea to add a simple "isRangeOf" template to Phobos:

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