A Tour of Standard ML
To this day, I don't understand why Google made Go instead of working off of SML. While the go ecosystem is better due to the millions of man-hours poured into it, the language is inferior in every way.To elaborate, CML is better than golang's channels and isn't broken (requiring mutexes over channels to avoid breaking qualifies as broken). SML syntax is simpler to learn, but still offers much more powerful abstractions with pattern matching. SML uses options instead of null pointer exceptions. Hindley-Milner types are clearly superior to Golang's type system (especially things like empty interface). SML has had generics for almost 25 years now while go languishes. SML has immutable data structures and they are the default for almost everything. Golang has implicit types, but SML's implicit types are much better -- especially structurally-typed records. SML's modules are amazing and simply have no comparison in go. Finally, SuccessorML is doing work toward adding a few new features to the language (for example, module type classes), but the language has an actual specification that anyone can implement (and many have) rather than the implementation effectively being the spec.
