Hoyt: Structural pattern matching in Python 3.10

Ben Hoyt has published a critical
overview of the Python 3.10 pattern-matching feature.

As shown above, there are cases where match really
shines. But they are few and far between, mostly when handling
syntax trees and writing parsers. A lot of code does have
if ... elif chains, but these are often either
plain switch-on-value, where elif works almost as well, or
the conditions they’re testing are a more complex combination of
tests that don’t fit into case patterns (unless you use awkward
case _ if cond clauses, but that’s strictly worse than
elif).

(Pattern matching has been covered here as
well).
