Now that I am learning how to work with complex data structures, I
find myself writing things like this a lot:
my $foo = ( defined $very_long_expression ? $very_long_expression :
"n/a" );
or
my $foo = ( $very_long_expression > 0 ? $very_long_expression : 0 );
(Where the long expression typically involves dereferencing hashes of
arrays of hashes.)
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,
Chap Harrison
