I am not a keyboard warrior who got caught up in the nonsense, but I think some people were simply annoyed at adding syntactic sugar for very marginal benefit. “There should be one way to do things” mantra.
I have a long list of grievances with Python, but the walrus situation would never crack my top ten. Put effort into removing cruft from the standard library, make typing better, have the PSF take a stance on packaging. Anything else feels a better use of time.
Whatever, it won. I will never use it, but when I see it will have to scratch my head and lookup the syntax rules.
It was against many people's aesthetic sense. Including mine. But in theory it can be ignored completely, and in practice it is barely ever used (and indeed nobody forces you to add more uses).
If you already know Perl, Raku is easy to pick up. Especially for basic text munging tasks. The RegEx stuff has changed though. Takes some getting used to.
Some of the warts are gone (like a list element needs to have a scalar context, the stuff that scares away beginners).
It is a _large_ language with paradigms and constructs that are from everywhere (ML, Haskell, Lisp, C, Perl you name it).
Powerful operators. Actually too powerful. Easy to write elegant line-noise kind of code.
Easy to use built in concurrency. (There isn't much that is not built in :-) )
Nice language for Sys/Ops scripting if you find Bash too dangerous and Python too tedious.
Not just too much stuff IMO. I kind of like all the features.
The main problem in my eyes is not enough volunteers (although they are doing a superhuman effort) to get it into the production level it needs to get more widespread adoption. The other problem is that Python already has a huge amount of libraries and is considered to be "good enough" feature wise, so it's hard to attract interest.
I do enjoy reading Raku code and think it is super neat as this do it all post-modern language. Inertia is hard to overcome though.
Early on, there was some attempt at syntactic macros. I tried it. But it didn't work out. I hear there are efforts for another iteration. That would be just fantastic when it lands.
