Oops, ok;  There are only a few places where the API exposes
expressions, currently,

  ASSwitchStatement#getCondition()
  ASIfStatement#getCondition()
  ASField#getInitializer()

so lots of the Statatement interfaces need extending.


FYI, I suspect that not all kinds of expression have a representative
interface yet (most of my own use of the API is for generating new code,
and I've just been extending the API when I want to generate a new
construct).  I'm thinking of conditional-expressions 'a?b:c', and
'dot'-expressions 'a.b', which might be a property access or a class name
(but we can't tell without doing a bit more semantic analysys).


What changes would you like to make to the code?  I'd be very happy to
help!


ta,
dave
