Sergiu Dumitriu updated VELOCITY-681:
-------------------------------------
Description:
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).
