Fellow Monks,

I have both a quick question and then an extended question.

First things first.

I want to pass a value to a class method. If the value is undef, then I want it to immediately return undef. This is generally something that I'd look up in the Camel book, but since it is not around, please help:(. I am torn between

#This
my $RootDirectoryCanidate= shift() or return undef();
#and That
my $RootDirectoryCanidate= shift() || return undef();

The question is which one should I use to accomplish my requirement?

Second things second

\\//\\//hy would one be better than the other. I have a vague memory relating to precedence, but (as you can tell since I am asking) I can remember it:<
