Inconsistent type inference behavior of block-type vs expression-type closures

[stereotype441]

Consider the following code:

typedef num FunctionReturningNum();

main() {
  Object o = 1;
  FunctionReturningNum a = () => o;
  FunctionReturningNum b = () { return o; }
}

Type inference currently infers a return type of Object for the closure in a, and a return type of num for the closure in b.

The behavior of expression-type closures should be changed to match that of block-type closures.

This no longer seem to be the case. @stereotype441 can we close?

This issue was fixed in the front end in b755025. But this bug is about the analyzer. Since the analyzer hasn't yet been migrated to the front end, I am planning to replicate this bug fix in the analyzer. So I would like to leave this bug open until then.

OK, thanks for clearing that up.

@stereotype441 The example above no longer reproduces on bleeding edge. Should we close this?
