The second hardest problem in computer science is cache invalidation.
The *hardest* problem is naming things.

what do we call the vertical and horizontal line elements? I want to make
them configurable, which means the user has to be able to pass an argument
that specifies them. I have names for the individual components:
XXX = namedtuple("XXX", "vline tee corner")
default_YYY = XXX("│ ", "├─ ", "└─ ")
bold_YYY = XXX("┃ ", "┣━ ", "┗━ ")
ascii_YYY = XXX("| ", "|- ", "+- ")
def draw_tree(tree, YYY=default_YYY):
...
but what do I call XXX and YYY?

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure
enough, things got worse.
