Language design request: Take from Rust Algebraic types, ahead of time compilation and strong types, functional features, a borrow / escape checker that automatically turns shared data into Rc or Arc, as necessary, instead of tormenting me to rewrite performance irrelevant code; Take from Python the simple syntax, default pass by reference of all non-numeric types, simplified string handling, unified slice and array syntax - and any other simplifying feature possible. ... and give me a fast, safe and powerful language that gets out of my way while maximizing the power of the compiler to prevent bugs. Golang was a commendable attempt, but they made '70s design decisions that condemned the language: mandatory garbage collection, nullables, (void*) masquerading as interface{} casts, under-powered compiler etc.
