--- Comment #1 from Mathias LANG <pro.mathias.lang at gmail.com> ---
Closing as WONTFIX.

Rationale: This is an enhancement request, but there doesn't seem to be much
interest in it, and the rationale is limited. Proper exception hierarchy is
something that is often theorized but very rare in practice, and D is no
exception (pun intended).
If you strongly feel like we should pursue this, feel free to open an DIP:
