I disagree about binding only being a language thing:
# Happened to me in Perl 5 today
sub foo ($long_parameter_name) {
return 42
if (my $short := $long_parameter_name) == $specialcase;
...usual processing with $short...
}
push @foo, (my $head := pop @grtz);
(my $alias := $long_name).grtz();
# etc.
(Unless of course, you consider this to be obfuscation.)
