Version 1.2.0
=============
Bug fixes with breaking script changes
-------------------------------------
Bug fixes (potentially script-breaking)
--------------------------------------
* As originally intended, function calls with a bang (`!`) now operates directly on the caller's scope, allowing variables inside the scope to be mutated.
* As originally intended, `Engine::XXX_with_scope` API's now properly propagate constants within the provided scope also to _functions_ in the script.
