(Ovid) Re(3): Coderef from scalar.

This is often true, so I can understand why an eval might be necessary. What, exactly, is the source of the scalar? Is this being built at runtime? If so, eval might be the answer. If it's a bunch of static code snippets that can be determined at compile time, a hash of coderefs is faster and safer.

Cheers,

yes ... it's part of a programmable IRC bot, using Net::IRC. the "special function" is Net::IRC::Connection->add_handler(); so, yes, it's getting the code at runtime... I'm wanting to implement a ircbot with features similar to Everything(tm).	[reply]

If the code is coming from untrusted sources, definitely look into using Safe.pm and restrict the hell out of the permitted opcodes.	[reply]
