[erlang-questions] guard expression restriction

I think most useful guards expressions can be composed from guards.
Using macros you can bundle these and parameterize them to get
'user-defined' guards.  You can then put these macros in a header and
include them.

Macros seem like a practical solution to this problem.

Am I missing something?

RefactorErl, Wrangler or Dialyzer could be modified to "upgrade" or at least produce warning in all* cases where flipping the functionality would effect the true functionality of it. Also i would guess much code is written with out the knowledge that some LC guards fail silently, some don't  :-)
