Sure, but I find that a common syntax does help looking at the
similarities and differences of the existing rule based and pattern
based languages.

I agree that the correspondence is probably one way (a pattern may be
written as a rule but a rule cannot always be written as a pattern).

On the other hand, rule that can be expressed as patterns use to be
simpler to write and understand as patterns than as rules.

I strongly believe, then, that a pattern based language allowing to
define additional local rules would be a good compromise.

And that a common syntax does help top get the picture...
