just dont ask about unicode
Unicode support in Ruby has been great since the beginning.
Before that, Ruby did "support encodings" in a sense, but a lot of the APIs were byte oriented. It was awkward in general.

Btw, OCaml also transitioned from read-write Strings to read-only Strings, and Buffer to be that read-write string. It was introduced in 4.02 released September 2014. I recall it was a bit bumpy, but not all that rough in the end. I suppose static type checking helps here to find all the ways how it could be used. There was a switch to allow running old code (to make strings and buffers interchangeable).

> all optimizations from compiled / statically typed / lower level languages Mutable strings are totally possible (and not even especially hard) in compiled, statically typed, and lower-level languages. They're just not especially performant, and are sometimes a footgun. > all those complicated features right from the start Arguably, mutable strings are the more complicated feature. Removing them by default simplifie…
> They're just not especially performant What? Mutable strings are more performant generally. Sometimes immutability allows you to use high level algorithms that provide better performance, but most code doesn't take advantage of that.
TIL that Ruby has mutable strings, and (until the announced change) even had them mutable by default (and the change only affects literal strings; non-literal strings are still mutable). Python has always only ever had immutable strings.
In Ruby you tend to use :symbol for small immutable strings << is inplace append operator for strings/arrays, while + is used to make copy. So += will make new string & rebind variable
Good reminder that anyone can go on the internet, just say stuff, and be wrong.

I’ll just kill the comment. It said Symbol isn’t garbage collected. It has been since 2.2 and I wasn’t aware. Sorry. Good reminder that anyone can go on the internet, just say stuff, and be wrong.
