Re: Calling conventions. Again

All~

This might have already been suggested, or their might be a good reason 
why not to do this but here is my idea.

Why not have unprotyped calls pass an array in P5 and a hash in P6?  The 
array can hold the first n positional arguments (possibly 0, for which 
Null could be passed to avoid creating the array) and the hash can hold 
the remaining m positional or name based arguments (also possibly 0).

Prototyped calls, then pass things in the exact registers they need 
I5-I15 for integers, S5-S15 for strings, etc...  and protyped calls can 
only be made when the full types are EXACT (i.e. no default values, or 
anything else...).

This allows the speed freaks to have a fast prototyped call with no 
runtime checks, and us mere mortals can go the slow way...
