It's not hard to give a phrase structure grammar for first order
logic, but such a grammar will not do syntactic justice to bound
variables. Something more is needed for any language with bound
variables that will at least do justice to their substitutivity.
One approach keeps a list of free variables along with the phrase
structure of the expressions and removes variables from the list
where they are bound.
