I believe the #if is minimally more economic than a #set, and for
sure does not pollute the context namespace. Also the #**# was for a
small bug in 1.4, where the if-block failed parse if it was empty.
If by economic you mean performant, I would argue that #set is
probably faster. However, your call macro is a more general solution.
Another possibility:
#set($list = $list.add("a").add("b"))
