I'm not sure I follow.
<!--- c1.cfc --->
<cfreturn "This is F">
<!--- c2.cfc --->
<cfargument name="func" type="any">
<!--- caller.cfm --->
<cfset copyF = createObject("component", "c1").f>
<cfset o = createObject("component", "c2")>
This grabs the f() function out of c1, passes it to g() in c2, where it's
A function (UDF or CFC method) is pretty much just a variable in CF, and
can be passed around as such.
You *would* have a problem if f() referred to other methods or variables
within c1.cfc, because by the time you're running it, it's not the method
that is the member of an instance of C1; it's just "some ol' function". So
anything it *references* must be available in whichever scope it ends up
