how to do iota(0,256) with ubytes ? (cf need for iotaInclusive)

[Timothee Cour via Digitalmars-d]

how to do iota(0,256) with ubytes ?
and more generally:
iota with 'end' parameter set to max range of a type.

of course this doesn't work:
auto b=iota(ubyte(0), ubyte(256));
//cannot implicitly convert expression (256) of type int to ubyte

Could we have a function with iota_inclusive that has inclusive bounds for
'end' parameter ?
