a function will either succeed or it will not return.

if invoke error is mapped to throw exception then it will never return. If
it's mapped to something else - like emitting an error message or invoking a
user specified call back then it won't throw an exception.
That results in a really horrible API with dual error reporting mechanisms.
FYI - it's not a dual reporting mechanism.  It's leaving the choice of 
reporting/handling mechanism to the library user.  Once he selects it, 
that one is it.
