Re: [Phrame-devel] MVC sample application

[Arnold C. <arn...@ya...>]

The analogy to verbs, nouns, and adjectives is exactly
how I described phrame to developers as well.

I have reservations about removing forwards, forms,
and actions.  They provided extension points for
specialization if required.  Using primitives removes
this important feature.

My understanding from studying Tony's code is that
commands are a simpler version of the original
actions.   This mechanism is basically just a command
pattern with the exception that actions utilized the
mappings and form objects.
