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).
