Hmmm ... maybe I need some enlightening, but this is what I came up with ...

> cat a.rb
def if(*a) p a end

if true then puts 'keyword 1' end

if(true)
  puts 'keyword 2'
end

> ruby a.rb
keyword 1
keyword 2

and invoke the appropriate function via the lexer.  Unless I did not
properly define my "if" method there.
