This isn't even remotely a major bug, but the latest experimental version of Monkey has a small bug with '_env' again. The 'InvokeSuperExpr' class's 'Semant' method uses '_env' (Found in 'trans.expr'), but it for some reason doesn't exist under this situation. Here's the exact line causing the error (Memory access violation, because '_env' is 'Null')

The exact version I'm running is V82(B). The only changes I made were rebuilding 'transcc', and that GLFW3 fix you did for keyboard input; both not relevant.

It makes me wonder why we can't use super for constants, like what I wanted to do.

Here's a test I made when I was checking if 'Super' could be used like this:

Strict

Public

' Imports:
' Nothing so far.

' Functions:
Function Main:Int()
	' Local variable(s):
	Local X:= New Z()
	
	Print(X.W)
	
	' Return the default response.
	Return 0
End

' Classes:
Class Y
	' Constant variable(s):
	Const Test:Int = 30
End

Class Z Extends Y
	' Constant variable(s):
	Const Test:= Super.Test+1
	
	' Fields:
	Field W:= Test
End

Not a big deal, but it's a bug, and I had to move to a debug build of 'transcc' in order to see what was happening. Newer Monkey users might go crazy debugging their own code over this, though. At least I got my answer, though.
