I've had occasions where $bar->{url_target} is actually a deeply
nested data structure (thank you XML), so:
$bar->{fu}{man}{chu}{with}{a}{lemon}{twist} ?
do_something_wise($bar->{fu}{man}{chu}{with}{a}{lemon}{twist}) :
or_not($bar->{fu}{man}{chu}{with}{a}{lemon}{twist})
is pretty painful. On those occasions I've done:
($_ = $bar->{fu}{man}{chu}{with}{a}{lemon}{twist}) ?
do_something_wise($_) : or_not($_)
It's a little more obtuse, but you'r not a likely to fat-finger the
reference. The downside is any possible side affects of using "$_".
