Thanks all for the input.
crashtest, i use:
use FindBin;
use lib "$FindBin::Bin/PathWithModulesOfMyApp";
so i don't need to have "/" or "\" in $op, that's why the regexp is so strict.
The reason to ask, is that imho "require" makes a BIG securiry issue, when the regexp is missing, you'd be able to do things like this
http://127.0.0.1/cgi-bin/script.pl?option=%60touch%20/tmp/HA_I_CAN_WRI
+TE_ON_YOUR_HARDDISK.txt%60
and think of more nasty things to do.
That's what
Tanktalus warns about, and that's why i'm wondering if there is a way to avoid the use of eval totally.
I'll have a look at
UNIVERSAL::require and
Class::Inspector as well, more options are welcome.
