Enhancing foreach

[ixid]

I think you're rather a long way away from beginners to see how 
beginners would think. iota is behaving like the Python range 
syntax which beginners seem to find quite easy to use. A beginner 
thinks 'it goes up to that number', the thought process you 
outlined is that of someone learning their second or third 
language.

Is that any different to the current for loops not doing what you 
meant if you don't type things? It doesn't seem subtle nor an 
unexpected behaviour, there's no shortage of cases where if you 
omit bits of code it'll do something else. If this was supposed 
to be a normal for loop the user's forgotten to give i a type and 
a boundary condition and the second semi-colon, that's three 
errors, the space of different behaviours you can get to in any 
given piece of code by making three errors is probably quite high.
