In my mind other compilers are of course free to use the {-# ... #-}
syntax has they see fit and GHC has no other choice but to accommodate.
Arguably the report should have just specified that the {-# ... #-}
syntax as namespaced, avoiding this whole situation.

In the case of tools we have the opportunity to correct this mistake
since no strong convention has established itself yet. This is what I am
advocating that we do.
