also, workarounds involving:
iota(0,256).map!(a=>cast(ubyte)a)
are neither pleasant nor efficient

Anything less then 32/64-bit is actually a tiny bit slower due to having 
to mask away top 8/16 bits since most of parameters passing and 
arithmetic is done on full words. Anyhow cast is 0-cost.

    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 ?
