in reply to Avoiding Greenspun's Rule; scripting within Perl

Many projects I've been writing lately have included the ability to use Javascript via JavaScript::V8. It is cheap and it is blazingly fast and if you are a web shop then you most likely have a team that already speaks Javascript.

I'd like to use perl as an embeded language inside of perl, but I have yet to see a safe ( locked down environment. Javascript isn't perfect as they could still consume all memory, or write an infinite loop, but there is no danger of it having access to more than I give it.

my @a=qw(random brilliant braindead); print $a[rand(@a)];

    I've not used JavaScript::V8, but have used JavaScript::SpiderMonkey and JE (the latter of which is a pure Perl javascript implementation!) and find Javascript to be a good choice for this sort of thing.

    I have also taken a look at the various Perl Lua offerings (Inline::Lua, Outline::Lua, etc), but none of them have impressed me much. I can't seem to find a way to, for example, lock down Lua's file IO functions, so it doesn't seem to be useful as a sandbox. (It might be possible with Lua::API, but that module is very low level and I've not had much success with it.)

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
