Is naming the real confusion or is it existence? I know Pants fairly well and am continually bamboozled by the fact I need to lay down an empty

python_library()

declaration for my

pex_binary(...actual metadata I wrote down...)

to work. Whether the - what looks like a no-op -

python_library()

was a

foo()

or a

bar()

I'd still be mystified by the need. I can go read excellent docs that explain this to me, but at that point the newbie game is up and I can learn what

python_library()

the word means.
