This has been discussed previously here at the monastery, but I can't seem to find where. The general consensus is that it is not possible. The perl -c trick will not prevent code from being executed; see the following, for example:

[chmrr@supox chmrr]$ perl -c
BEGIN {print "Nope!"}
Nope!- syntax OK

perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'
