Depending on code review instead of a static type system does not scale. Look at all of the memory safety security vulnerabilities that are solved by "simply making sure to manage memory correctly."

Also:

  variableDefinedInAFarAwayModule := 17

  ...

  TestSomething(variableDefinedInAFarAwayModule)
  

It's not always as clear as a constant value being passed to an incorrect type.

I don't understand your example here, that's not going to compile.

variableDefinedInAFarAwayModule is definitionally type int and will not be cast. It is also unpublished, so you couldn't be using it for a faraway module?

Your 17 in the previous example has it's typed determined at compile time which is why it can be a problem.

Ah thank you. That's slightly better then.

This will not compile because the type of the variable is int not Test.
