Why shouldn't the compiler allow to modify a loop variable? It is sometimes 
useful.

Why shouldn't the compiler allow to return from inside a loop? It is perfectly 
valid to do that.

A bad programmer using some syntax for writing bad code does not necessary 
imply that that syntax should be forbidden.
