Hi,
I used a macro for this purpose:
#macro( call $foo )#if($foo)#**##end#end
...
#call( $list.add("a").add("b") )
...
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.
Regards
Christoph
