Range returned by iota and const

[André Stein]

Hi,

I'm trying to pass the range returned by iota to a function accepting 
the parameter as const. I got compilation errors when trying to use the 
index operator and after some investigation it turned out that opSlice 
of iota.Result isn't declared as const.

The function body of opSlice of iota.Result doesn't seem to mutate the 
range so is there any special reason why it isn't declared as such? (the 
same holds for opSlice).

Regards,
André
