Enhancing foreach

[ixid]

A very minor change that would be elegant and easy for beginners:

foreach(i;5)
     //stuff

Allowing just a single number to mean the end point and a default 
starting point of zero is assumed, just as with iota it's 
possible to write it iota(5) or even 5.iota, it assumes unless 
otherwise specified that you mean 0 to be the starting point. 
Would this be a reasonable enhancement request for me to make or 
does it collide with something?
