      Algol (1958) is the spiritual parent language of the C/C++/C#/Java family. It introduced the accursed "int x" syntax which Niklaus Wirth tried to undo with Pascal and other designs. Yet the notation persists and perpetures a 60-year confusion around types and values.

      The confusion is this: In some places "int" means "the type of all integers", such as in "array<int>". Elsewhere it's an indeterminate placeholder to be filled in with an actual integer, such as "void f(int x) {return x+1;}" or "int f(int,int)".

      This confusion doesn't exist in Pascal or Typescript syntax. "int" refers to the type, and ":int" is always an abstract placeholder for a particular value. The type-value dissonance is stretched to the breaking point when they're mixed as in C++ template partial specialization.

          Scala was one of the "new" languages that picked up on the pascal notation, which is not that strange, since Odersky was a student to Wirth...

          and in haskell's f :: int -> int, what would you call either instance of the string int?

          I think you're in an interesting position. Epic has done so much with a language you seem increasingly unhappy with. For projects I drift to when idle, the bottleneck is always my brain's limited rate at clarifying the logic I want to implement as opposed to language features.

          Isn't this handled in Java with int and Integer class

          I have many problems with C's syntax but this is not one of them. int is always a type, the variable/constant that holds a value of that type is the identifier right next to it. i:int or int i, both are of type int and are named i. Pretty obvious for me.

          The ugly part of C is that you can omit the parameter name. And that this here can be different things: A b(); But a "var" Keyword could fix that, or a "func" keyword, or both
