Instead of adding new runtime helper functions like _d_newThrowable and _d_delThrowable, can we leverage the existing (though deprecated) support for class (de)allocators and essentially divide the _d_delThrowable implementation between the destructor and the deallocator member function? This will go hand in hand with the work that Lucia has been doing on making the runtime more generic and reducing the number of special cases in the compiler [1] [2] [3]. Obviously you have done the work already, but in theory at least, with my proposal users should be able to override the memory allocation method in derived exception classes, without any changes to druntime.
I considered that, but discarded it because then all Throwables would be allocated that way, in a completely uncontrolled manner.
