Comment:

 Bumping the importance of this since you really should be able to use
 pattern synonyms in a manner without compromising performance.

 I agree that a simple `INLINE P` pragma should inline both the matcher and
 the builder. Indeed we could expose `INLINE_MATCHER` and `INLINE_BUILDER`
 variants as well, although I am doubtful that they would pull their
 weight.
