Lambda Tree API changes feedback

[Michael Nascimento]

Hi,

Some feedback / questions:

- What is the purpose of having a special getBodyKind() in
LambdaExpressionTree? Why isn't the regular getKind() in the Tree
returned by getBody() enough?
- Isn't the grammar in MemberReferenceTree supposed to use :: instead of #?
- Any reason for not providing a super interface between
IntersectionTypeTree and TypeParameterTree or MethodTree and
LambdaExpressionTree?

Great work, guys, I didn't expect the Tree API to be updated already.

Regards,
Michael
