Strict

Function Main:Int()
	Local test:Test = new Test()	
	test.a()

	Return 0
End

Class AbTest Abstract
	Method a:Int() Abstract
End

Class Test Extends AbTest
	Method a:Int()
		Return 1	
	End
End

This code throws "Missing return statement".

Thanks for the quick fix Mark :)

I notice that the exes have been updated but not the source files (I guess Im looking in decl.monkey).

Hi,

Ok, turns out this quick fix borks a few other things in Java/C# - fix in haste, repent at leisure!

I'm going through strict mode pretty thoroughly right now (my bad - I never use it so it tends to get ignored) adding smarter code reachability detection and just generally cleaning up some bits that have grown a bit ugly over time.

Hi Mark!,

I'm getting a Cannot convert from {NULL} to Int[] error in this method. I don't if it's one of those borks you mention (tried in GLFW).

	Method getIntArray:Int[](name:String)
		if dataIntArray.Contains(name) = True
			Return dataIntArray.Get(name).i
		Else
			Error("Undefined variable "+name+" for IntArrayMap.")
		EndIf
		Return Null
	End method

I think this should be allowed to Return Null

Hi,

Nope, that's correct.

Arrays and strings in Monkey are NOT objects, therefore they cannot be Null.

You can however return an empty array, ie: 'Return []'
