Hi Vasanth,
a lambda EG member here,
detecting the creation of a lambda is easy, you just have to lookup up
an invokedynamic that use the LambdaMetaFactory as bootstrap method.
So there is no need to have a support of invokedynamic in Graal,
detecting this peculiar pattern is enough.

The bootstrap arguments of the bootstrap method will give you the
code of the lambda, I suppose that you need to re-build an AST
(or a kind of) from the code of the lambda.

cheers,
