Hi,

recently I've done things like this (sorry, I am a bit drunk and too lazy to look up the actual code - but you get the gist...): 

my $subtree = $dom->find($whatever);
$subtree->delete if $substree;

[download]
And I was wondering if there was a better way to do this, some kind of Groovy "safe navigation" operator that would allow one to write: 
#pseudo-code - does not run!!!
$dom->find($whatever)?->delete;

[download]
i.e. a method-invocation that would check if the receicer was defined at all and simply does nothing if the receiver is undefined.

I ask because something in the back of my mind tells me that I may have heard something to this effect at a conference, but as I said - I am a bit drunk...

Many thanks!
