when i first started to use Limbo, which has a similar looking
idiom, i thought the same.
for(i := 0; i < 10; i++) {
}
but actually, having the variable
available outside the scope is so often useful,
e.g.
for(i := 0; i < end; i++)
if(sometest())
break;
if(i == end)
fall_through_condition();
that i now think the non-scoping behaviour is the right thing.
i'm not sure that it's worth adding to plan 9 C though.
