At some point I thought I read about a shorter way to write this, that
did not involve repeating the $very_long_expression in the same
statement. Perhaps a special variable or something, acting sort of like
a pronoun. Anyone know of a shortcut?

Thanks,

Well, if you're able to upgrade to 5.10:

my $foo = $very_long_expression // "n/a";
