( #3333=superdoc: print w/replies, xml ) Need Help??
My favorite special variable is good old $_.

Yesterday I realized that it is Perlish to assign variables to $_ explicitly. For instance, I can say:

$_ = "LamourEstBleu"; if (/Bleu/){ print; }

At one time I would have considered the above snippet to be obfuscated, because to a novice Perl programmer it is saying "Print something, but I am not going to tell you what to print."

Now I see that this Perlish way of using $_ can make code clearer, by not repeating the variable name over and over again.

If a variable is a proper name, then $_ is like the word "it". Most of us when speaking French/English whatever do not refer to a subject explicitly every time, but use implicit references like "it" as well, where the meaning of "it" is apparent from the context.

Similarly, the meaning of $_, which is like the word "it" in spoken language, is apparent from context. As we deepen our own Perlishness I believe that many of us will use $_ more and more often. I know I will!
