methods that might return null

How do people handle the case where the return value for a method
might be null?  If you are calling the method in a loop, it looks 
like you have to call the method twice:

#foreach ($arg in $arglist)
   #if ($obj.method($arg))
      #set ($rtn = $obj.method($arg))
      ... do something with $rtn
   #end
#end

Is there a better way?

Thanks in advance,
