[Issue 6447] iota(BigInt) too

--- Comment #13 from bearophile_hugs at eml.cc ---
I keep this issue open because this still doesn't work:


void main() {
    import std.bigint: BigInt;
    import std.range: iota;
    iota(BigInt(1), BigInt(100), BigInt(5));
    iota(BigInt(1), BigInt(100), 5);
}



test.d(4,9): Error: template std.range.iota cannot deduce function from
argument types !()(BigInt, BigInt, BigInt), candidates are:
...\dmd2\src\phobos\std\range\package.d(4008,6):        std.range.iota(B, E,

isPointer!(CommonType!(B, E))) && isIntegral!S)
