I'm thinking that maybe Check Syntax shouldn't do any coloring that the
online colorer can do; instead, it will become a tool for exploring the
lexical structure of the program (jumping around between variables,
jumping to definition sites in external files, showing the tail-call
structure, etc), in addition to the usual function of finding any
syntax errors.
