grinder,
No, I assure you I know they are different and completely understand why postfix is wrong. Please read my response to dragonchild. My questions are specific to this construct.

The reason we don't do: 

if (some_func()) {
    my $val = some_func();
}

Is because some_func may change return values in subsequent invocations. The reason why we don't do: 
my $val = some_func();
if ($val) {
    # ... 
}

[download]
Is because we want $val scoped as small as possible.

This only works because of the implicit scoping in perl 5 which is going away in perl 6 (at least in for blocks). I am wondering if there is an alternative way of writing this that accomplishes both things.

Cheers - L~R
