I'd like to understand the proposed semantics better, to see what's
actually being proposed and how it interacts with a world in which
multiple globals exist.
Given this:
try {
something();
} catch MyError (e) {
// when do I reach here?
}
when does control enter the catch block, exactly? Is it when "e
instanceof MyError"? Is it when "e.name == MyError.name"? Something else?
