But MSVC doesn't know how to auto vectorize it, which kind of defeats the purpose :-( :-(. GCC does though:

They ruined it a long while ago when they removed the ability to actually search for videos matching strings as opposed to "videos that I think you want to see because you typed this pattern".

Mastodon let's you edit posts.that big enough to make the choice clear

I don't want it mixed up with my largely inactive FB and Instagram accounts. Can I make a separate threads account under the same email address as those?

Is this thing on?

I've made both mastodon and bluesky accounts to replace twitter so I can check them out and decide which to keep.

c++ should have an abbreivated lambda syntax for simple functions. Like:

[]( int arg ) = arg * 2
