Monks,

There has been much discussion recently about argument passing, see Shift versus Sanity and Sub::HashWrap.

Glancing at the Camel book, I was reminded of the pragmatic module use fields in the context of validating data fields in an object at compile time. The underlying mechanism used is a pseudohash.

I was wondering whether something similar could be used for named arguments to a sub or method, detecting typos at compile time.

I also understand that phashes are an experimental feature from 5.5 on, which could change. Are they here to stay? Are they OK so long as you use fields::phash?

Thoughts please. --rW
