This seems like a legitimate place for "saying what you intend", viz:
for (my $n is longlasting = 0, $m = 1; ...) {...}
Albeit that's a lame example of how to do it.
What's not clean about
{
loop my $n = 0; $n < 10; $n++ {
...
}
}
? Works fine for me, shows the scope boundaries very clearly indeed,
just the kind of thing a lot of languages are missing, IMO.
Of course, this example's really bad because it's much better written
for 0..9 {
...
}
In which case I assume that it only clobbers the topic inside the
block, not outside it, as it's somewhat like
for 0..9 -> $_ {
...
}
To write it explicitly. Or am I barking up the wrong tree completely?
Not sure. In my example, there were two variables, 'n' and 'm', one of
which was supposed to outlast the scope, the other not.
