Golang is my other language, and i must say it’s really one of my favorite, mainly due to all the things it chose not to do.
Just wait, generics weren't going to happen, and then they did.
took them 10 years though.
One major addition to the language every 10 years is a good rythm. Also, their addition of generics felt super natural and didn't change the general feeling of the language.
Compare that to swift that has added await async, macros, move semantics, actors, in just a few years, while keeping everything that was already there...
So now we have both gcd and actors, both macros and the hack they used for swift UI, and yet xcode integration is still awful, and there's still no decent story for cross-platform development (just compiling for android for example).
It's a mess..
C# 12 with .NET 8 standard library, Java 21 with standard library, Python 3.11 with standard library, plus knowing key versions on their timeliness, and major third party libraries are just as complex.
So nope, it is impossible to know everything.
Even those that claim to fully understand "simple" languages like C, they actually master their own C compiler and are unaware of all variants and deviations of it.
