"if x is not var y" not working

[hpetriffer]

The following code is not working (if block is not called):

	if uSwitch is not logic var bSwitch
		Console.WriteLine("uSwitch is not logic with var")
	endif

if var bSwitch is removed, the code works fine

	if uSwitch is not logic
		Console.WriteLine("uSwitch is not logic")
	endif
