I see something to do to continue the DIP

SpecialTokenSequence:
     SpecialTokenSequencePrefix line IntegerLiteral EndOfLine
     SpecialTokenSequencePrefix line IntegerLiteral Filespec 
EndOfLine
     SpecialTokenSequencePrefixes Keyword

SpecialTokenSequencePrefix:
     #

SpecialTokenSequencePrefixes:
     SpecialTokenSequencePrefix SpecialTokenSequencePrefixes


Which means that you can use As many # as you want to escape a 
keyword.
Mixins cannot introspect themselves so basically 'pound pound' 
will always work.
And this is still a simple thing that can be done in the lexer.
