Hi! found myself coding a lot of ugly statements like this:
$foo = $bar if defined $bar;
This is fine unless $bar is a complex statement or a function that I don't want to call twice. Of course I could create a temporary variable which makes the code even uglier:
$tmp = bar(); $foo = $tmp if defined $tmp;
What I would like is a short and simple syntax where I only have to type each part of the conditional assignment once:
$foo =ifdef $bar
Any ideas? The code should be short and readable. Bonus points if $foo can also be a list.
