Perl iron-man initiative

Thursday, 23. April 2009, 12:08:13

Matt Trout of DBIx::Class fame has started an initiative to get people using perl to be more visible in the blogsphere. A good initiative indeed as there seems to be a huge and alive community using perl, but they don't seem very visible on the web.

Read his entertaining post about the initiative here.

I think a programming language that has things like "$$" and especially "$_" shouldn't be used at all!

Hades32:

most of the time using $_ is not necessary, sure it's ok for one-liners, but proper perl is written using explicit vars. (map, and grep are the only exceptions, but even then you should use explcit variables)

Instead of $$, I'd use:

use English qw(-no_match_vars);
print $PROCESS_ID;
print $PID;

(perldoc perlvar)

From my experience most people don't obey to such rules. Therefore I think the possibility itself should be removed. (From a syntax point of view I like perl much more than e.g. python...)
