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.)
