in reply to References for subroutines to Hashes in Hashes :)

You are very close. The trick to remember is that hashes and arrays can only store scalars. Perl can have complex data structures only because a reference is a scalar.

This means that your hash of hashes is really a hash of references to hashes. To pass the reference to a subroutine, then, you need only access the value. In this case simple remove the preceding slash ( sorry, I would try to use a code tag, but I am using Opera and it makes a real mess of things ).

Hth,

[Corion]: ambrus: AnyEvent(::HTTP) doesn't integrate well with Prima, that's my main problem
[Corion]: There is a weirdo shim because there is a POE integration for Prima, and if you use that, you can use the POE adapter of AnyEvent. What I'd want is something transport agnostic that parses HTTP or produces HTTP output, so that the communication with ...
[Corion]: ... the socket is done by my code. Ideally that module would not be based on callbacks ;)
