   This is not the case, unfortunately. There are already a lot of 
exploits written in Perl, Python. Just google for "perl exploit" or 
something similar. And this exploits are not like "construct proper GET 
request for another SQL injection", but complicated buffer-overflowing 
ones. Also exists some tutorials like this:

   As was said above, perfoming privilege escalation in scripting 
languages is not harder than in C, for example.

   So, using "noexec" option for preventing malicious code from 
execution is not desirable.
