Missing extractor for closures in Tasty Reflect

[liufengyun]

Currently we don't have extractors for closures in Tasty Reflect, nor do we have extractors for function literals.

We do have the closure extractor Lambda. unapply.

What do you mean exactly by function literal extractors?

Thanks @nicolasstucki . Currently we have the extractor for closures, which could be used to implement the extractor for function literals. We need to add the extractor for function literals.

For this case, we encounter a problem:

• what is compiler internal, what is language spec?

If portability is the design goal of Tasty Reflect (among different Scala compilers, different versions of Scala compilers), then it seems better to not expose extractor for closures, but only extractor for function literals. The existence of closures and its desugaring seems to be compiler-specific.
