Popular mail clients are designed to be popular, not to make that
expertise easy to acquire and exercise. Clunky use of email makes
lists much less pleasant for everyone than they could be.
I guess that's sad (I am, after all, a GNU Mailman developer), but
it's reality.
Personally, I'm sad because some people whose contributions I enjoy (you
being one of them :-)) didn't move to Discourse. But like you say, it's
how things are.
Christian - you can make named constants using class attributes (or an
enum):
class A:
M = "M"
match seq:
case A.M, A.M, A.M, A.M, *r:
return 4*1000, r
Basically, the "names are treated as variables to assign to" rule
doesn't apply to attributes.
I'm not sure how helpful that is (it's not particularly *shorter*) but I
think the idea was that most uses of named constants in a match
statement would be enums or module attributes. And compromises had to be
made.
Cheers,
Paul
Thanks a lot, everybody!
I have tried a lot now, using classes which becomes more readable
but - funnily - slower! Using the clumsy if-guards felt slow but isn't.
Then I generated functions even, with everything as constants,
and now the SPM version in fact out-performs the regex slightly!
But at last, I found an even faster and correct algorithm
by a different approach, which ends now this story :)
Going to the Discourse tite, now.
Cheers -- Chris
