Not really -- when switching language, TextMate learns that the  
switched-to language should be used for the current extension. And  
when switching buffer, it re-initializes language + settings. The  
latter, one could argue, it does a little too often ATM (synch  
settings) -- but TM is definitely not designed to have the same  
extension mean two different languages, although it can be worked  
around by having the grammar specify a “firstLineMatch”, like is done  
for the .plist/.dict files, which can be both old-style ASCII and XML.

If this is official syntax, I can add a rule to the Perl language  
grammar to support it.
