There's some, but mostly it is just separating bound variables from
keywords. Useful, but not earth shaking. It's the other aspects of
check syntax (the stuff with variables and tail calls) that are more
interesting and cannot be lexical (we both mean lexical in the sense of
lex/yacc, not lexical in the sense of bound/binding variables, right?).
