[Templates] RFC: Template::Provider::PAR - allows PAR directories in the INCLUDE path

[Andy Wardley]

Hi Nick,

Thanks for your efforts on this.

Yes and yes.

None that I'm aware of.

Not that I can think of.

Sure thing.

The only thing to be aware of is that the TT internals are being reformed 
between v2 and v3.  That will include some changes to the provider API which 
has got a few ugly corners that need smoothing out.  But given that one of the 
main goals is to make it easier to subclass providers, I'm hoping that the 
transition process will be as painless as possible.

I haven't finalised the design/API for the TT3 provider yet, but the main 
architectural differences that come to mind are:

   * Clear separation of the generic cache from storage-specific providers

   * Throw errors as exceptions.  No more returning pairs of values.

So if you, or anyone else has got things they'd like to change about T::P, 
trivial or otherwise, then now is a very good time to speak up!

Cheers
