Custom default exception handler?

I don't suppose there's a way to change the default exception handler without using a modified druntime? I'm not seeing one in the docs, but I could have overlooked something. Replacing a druntime function at link-time wouldn't be ideal because then druntime's handler couldn't be called as a

Overload sets and templates

This works: -- void foo(T)(T t) if(is(T==char)) {} void foo(T)(T t) if(is(T==int )) {} void main() { foo(1); } -- But if I move the int version to a different module, and try to alias it into the current module's overload set (like I can
