Hi guys,
honestly I didn't read through the whole thread, but just wanted to remind
you of what we collected about binding methods in the Apache Flex Wiki:
https://cwiki.apache.org/confluence/display/FLEX/Simulating+AS3+language+features+in+JavaScript+using+AMD+and+ES5#SimulatingAS3languagefeaturesinJavaScriptusingAMDandES5-Boundmethods
Maybe it helps / clarifies things!
Cheers
-Frank-
