Kyle Simpson brought this up on Twitter today and I think it deserves one
last look. Here's an example of the issue:
var sym = Symbol("description");
sym + ""; // Throws
Meanwhile...
var sym = Symbol("description");
String(sym); // "Symbol(description)" *
(* appears to be the convention that implementors have converged on)
This is the only time that a "thing" in JavaScript throws when it
encounters an implicit coercion operation. This detail appears to be
problematic in that it's an unnecessary divergence from the language's
normal behaviour.
