JS_DecompileFunction() might help, but it returns a string
representation rather than providing iteration function...  Its
internals (js_DecompileFunction() code) might help understanding how it
works, but it seems to only be dealing with private parts of the API. 
toSource() from javascript code, similarily returns a string (invokes
internal toString code).  I guess that possibly an iterator function
could be derived with string parsing to work on each element one by one,
however it then is very possible that a rather complex javascript custom
parser become necessary if any code analysis is required.

Maybe that through debugging API functions it would be possible in a
more elegant manner, but I personally have no experience with this API
yet and will let others (dis)confirm this...
