You don't understand the question. Lily input is space insensitive,
meaning that generally

  c4
  c   4 
  c
      4

all mean the same thing, i.e. a quarter c. This means that you can't
distinguish between


  c~   c
  c  ~ c
  c

    ~c

unless you introduce to a distinction between ~ followed by spaces and
a ~ which isn't. I think that it is bad idea, and I doubt whether you
can pull this off in lexer.ll at all.
