Perl script permission question

[Chad]

The question stems from an IRSSI irc client scripting tutorial site
found at the following URL...

http://juerd.nl/site.plp/irssiscripttut

"Because Irssi scripts are embedded in Irssi and not executed from the
console, they do not need to be executable. A permission mode setting
of 600 is enough for scripts in your home directory, 644 is enough for
system wide script installations. The shebang line is not required, as
this is only the case for executable scripts. "

How can a script actually run if it isn't executable?

Many possibilities. The most straightforward is if it is executed as:

perl yourscript.pl
