After reading a GitHub discussion on the matter
(https://github.com/gvanrossum/patma/issues/93), '|' now makes sense to me
instead of 'or':
- The use of the '|' character in Python seems to be going towards a union-like
operator (dict merging, PEP 604), which is definitely appropriate here.
- The clarity of '|' and 'or' can go either way subjectivity, but a use-case I
hadn't considered in my previous comment was nested pattern matching, e.g.
case (1 | 2 | 3, x) | (4 | 5 | 6, x):
case (1 or 2 or 3, x) or (4 or 5 or 6, x):
To me, '|' seems at least as clear as 'or' in this case, since it can be read
faster and doesn't chew up space. Spaces before and after '|' definitely help.
- As Tim noted, 'or' would exist as a solitary logical function in the current
setup. Although, a different GitHub discussion could possibly ressurect 'and'
(https://github.com/gvanrossum/patma/issues/97).
