Module setup argument validation

Hi folks,

I'm writing a module which is essentially a blob of glue between some 
other very useful Perl modules.

What I'd like to do is validate the parameters coming in to my module, 
some of which are for my own use, and others are destined for the other 
modules (encapsulated as hashes).

I'm currently looking at Params::Validate -- but my question is, are 
there any other contenders in the ring?

Things I require are type checking (scalar, hashref, etc), setting of 
defaults for missing options, and ideally, overriding of options to 
enforced values.

thanks in advance,
