There is no way in native JavaScript semantics to do the magic thing the web platform currently does, wherein (a) code is executed synchronously, but (b) exceptions thrown from that code bypass any surrounding `try`/`catch` blocks, and instead reach `window.onerror`.

Uh... Sure there is.  It's as simple as a function that catches the 
exception and then calls window.onerror, no?
