I don't know wether it's a Great Thing (tm), but it is at least a Godd 
Thing (tm)! I always see the underscore as a kitchen-sink variable. 
This comes from functional languages like OCaml, that use underscores 
just that way. Moreover, if you recognize "_" as such, you can make 
optimizations to bytecodes, for example if you do:

    _, a = my_function()

The compiler may skip generating bytecodes for the first argument, thus 
gaining a bit in speed. Not a big gain, but it worths if you use "_" a 
lot (using "_" is quite usual in functional programming).
