No, they are part of the syntax. The compiler (in Nim and other languages) can track which exceptions are allowed to be raised in a procedure and which aren't at compile time:

And golang knows what type of error can be returned at compile time.

    type FatalError error
    func foo() FatalError {}

Nim does too. The exception tracking is performed at compile time.
