docs: Returns a closure that pushed the given value onto a Machine's stack.
  
      We use this to embed stack pushes in the VM code, so that the interpreter
      can assume that all instructions are callable Python functions. This makes
      dispatching much faster than checking if an instruction is a constant
      (number, string, etc) or a Python function.
