Warning (better: disallowing altogether) about `=>` directly
followed by `{` should be enough to cover all cases. To express
that you really want a lambda returning a lambda, it can be
rewritten either as:
(x) => () { assert(x); }
or as:
(x) => ({ assert(x); })
This check can be done purely by looking at the tokens. Should
we someday introduce tuples with `{}`, the check needs to be
done after the node starting with `{` has been parsed to
distinguish between delegate and tuple literals.
It's good idea. I myself stumbled into this before.
