My very biased opinion:

Raku: weirdest thing ever. And perl was already weird. I still see it 
more as a toy.

Go: Okay-ish (apart from being somewhat ugly). Doesn't really make a lot 
*better*. Was meant to be easy and to build things "fast" AFAICT.

Rust: Kind of a whole new approach. It won't let you just "rush out" 
some code, it'll force you to do it right, all the time.
Initially feels like a nagging teacher telling you all the things you're 
doing wrong.
In the end it really helps. We've had quite a few surprises there, even 
when having to do bigger refactors or changes to adapt to changes in our 
dependencies - once you're through all the things the compiler complains 
about, chances are things "just work" again.
With literally every other language fixing the compile errors is the 
least amount of work, the next step is going through all the runtime 
crashes and hoping you didn't miss any (because you didn't test all the 
code paths) ;-)

Fast to *start* with, then feels like it won't let you do anything you 
want to do, and nothing will get done until you accept that the compiler 
is right and you're wrong ;-), then the speed will pick up more and 
more, and finally it's extremely slow to "master".
