hg: lambda/lambda/langtools: Handle non-static method references from static context. More specifically, if f is an instance method of Z whose signature is A, B->C, then #obj.f is of type A, B->C and #Z.f is of type Z, A, B->C.

[Kevin Bourrillion]

Hello,

Does this mean that we could replace

  Predicate<Employee> p = { e -> e.isPartTime() };

with

  Predicate<Employee> p = #Employee.isPartTime;

?  If so, very cool.
