How to pass a method into a function

please consider this code:

Strict
Type Ta
	Method b()
	End Method
	
	Function c()
	End Function
End Type

Local a:Ta = New Ta

test(a.b)
test(Ta.c)

Function test(z())
	Print "something"
End Function	

It won't compile because it won't let me pass a method b() into the test function. If you comment out the duff line, the function c() can be passed in fine.

Don't suppose there's another way to do this apart from turning my method into a function and putting "self." in front of anything important?
