> The fix for VELOCITY-615 was too radical, since it completely disables #setting new values to the formal arguments. A minimalistic example that used to work up to 1.6 (but not with 1.6.1) is:
> {noformat}
> #macro(myMacro $result)
>   #set($result = 'some value')
> #end
> #myMacro($x)
> $x
> {/noformat}
> which prints $x (as an undefined variable).
