[REBOL] Set with context (was Global function defined in context)

Hi List,

More on 'set with context, just to be sure...


A 'set construction, like the following, is used to define a global function using local 
(variable) "variables".

	>> myWorld: context [
	[     a: 10
	[     set 'helloA func [][print ["Hello " a]]
	[    ]
	>>
	>> a: 20
	== 20
	>> helloA
	Hello  10


The HelloA function, however global, is looking first in the context where it comes from.
Am I right?
