Comment (by chessai):

 Why would a pattern synonym not get inlined by default, always? Pattern
 Synonyms AFAIK don't perform any computation; only computation that may
 occur within a Pattern Synonym would be within ViewPatterns, but inlining
 any function inside of the ViewPattern shouldn't matter to just the issue
 of inlining the Pattern Synonym. Please correct me if I am wrong or
 missing something.
