I do think this approach have a flaw. If we go in that direction, then 
it push devs to create new Exception type just to catch them, because 
this is the only way we have.

If I understand properly your pull request, the compiler will be 
duplicating catch block ? If it is the case, would it be possible to use 
static if to use type specific stuff of E1, E2 or E3, depending on which 
one we are facing ?

BTW, great job, it is definitively a nice addition to have.
