Suggestion for automatic wrapping of checked exceptions inside RuntimeExceptions inside closures

[Martijn Verburg]

Hi Behrang,

In order to contribute something like this to OpenJDK, it's generally
requested that you discuss the semantics of the proposal in the correct
mailing list, especially before any before any discussion on syntax :-).
If you can formally write this idea up with the semantic interactions of
how this automatic wrapping will work and the benefit it might bring to
this list then there's a few folks who can help critique it before moving
onto core-libs or valhalla-dev.

Cheers,
Martijn
