One can even combine it with loop-var-aliasing!

lanx$ perl -e '
$a='a';$b='b'; my $var;
for $var ( $a,$b ) {
  *$var=sub {print "$var \n" }
};$var="x";
a();$b="y";b();
'
a 
y 
lanx$ perl -e '
$a='a';$b='b';  
for $var ( $a,$b ) {
  *$var=sub {print "$var \n" }
};$var="x";
a();$b="y";b();
'
x 
x

Obfuscators, here we are! ;-)

Well seriously, I think as a rule of thumb you discovered, that a "localised" lexvar my $var;for $var(){} has the same "closuring"-effects like a  for my $var () {} .

I bet they act exactly the same...
