Just food for thought: C# has a special syntax, inspired by its own lambda syntax, for single-expression functions:
> // lambda syntax > param => param + 4 > > // single-expression method syntax > int AddFour(int param) => param + 4; Swift's syntax for declaring functions and lambdas are harder to link like that though.
