There is U+FF3F Fullwidth Low Line.

You can use it in variable names, but not at the beginning, and it isn't
equivalent to two underscores, of course:
Python 3.9.0b3 (default, Jun 13 2020, 10:49:29)
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> ＿ = 12
File "<stdin>", line 1
＿ = 12

I have quite a bit of experience with various programming languages,
including python, C, C++, and lisp. But I very rarely work on projects
that use interoperability. This is something that I'd like to learn more
about.
Sometimes, for numerical computing, I use cython as a binding layer
between C++ and python, but that's the extent of my experience. I'm
under the impression that if one were to want to use something like lisp
(like say ecl embeddable common lisp), C, and python together, the
process boils down to writing a lot of wrappers in C. And more
generally, C is a frequent lowest-common-denominator language. Is my
understanding right?
