Until now there was a large discrepancy between x.f() and (x.f)() This CL makes x.f() as fast as (x.f)() by automatically generating a intermediate dispatcher function that loads the field and invokes the result as a closure. The approach resembles the one taken for fast noSuchMethod invocation and reuses the same per-class cache of dispatcher functions. It also fixes a bug in the debugger so that VM-generated implicit dispatcher functions (like for noSuchMethod, or field-as-method invocation) don't show up the debuggers stack trace.
