What about variables or functions created using eval?  Is it ok if those 
are not included?

In SpiderMonkey, you could parse the source and walk the parse tree 
yourself, using a "friend" API (subject to change, not frozen but not 
likely to change in a huge way; no binary compatibility).  Or you could 
compile to a script and then execute the script's prolog bytecodes, 
which process var, const, and function declarations.
