quick select set by "type" quick tip

Was just discussing how to quickly get a set of all your lights in a scene and thought I'd try some fast mel code, and low and behold it worked.. 
 super easy and fast and works great. 


this is one for  "meshes" :

 sets -name "meshes" `ls -type "mesh"` ;




oh and in python it looks like this

import maya.cmds

maya.cmds.sets(maya.cmds.ls(type="mesh") ,name="meshes")
