I don't expect a large number of member functions to exist there,
though.  At most one function looks for .git and another looks for
markers like venv (or like in my example doesn't look for markers at
all).

I really don't expect this to be a performance sink.  But since it's
easy to be wrong in these guesses, we can tweak the function that looks
for marker files .venv to only search if a current parent project is
there, just like my example.

If, on the other hand, the user's goal is to search for _both_ .git or
.venv (maybe she has some non-git venv projects) then we're just going
to have to look for two files and that's that.
