I solved it myself. I forget that I can use function as predicate
import std.stdio, std.algorithm;
class A: Exception { this(){ super(null); } }
class B: A {}
class C: B {}
class D: A {}
class E: A {}
class F: E {}
size_t countDerivations(TypeInfo_Class typeinfo)
{
size_t re
Also I have the following code but I get some error. I think it's
because of std.algorithm.sort function that uses mixin to inject
predcate. But it doesn't import symbols passed in predicate and
fails. Is there some way of resolving this problem or I need to
inject full code of function inside
// declare the function so we can access it (as an internal
druntime
// function, thee is no import to provide it, but we can call
it anyway)
extern(C) int _d_isbaseof(ClassInfo oc, ClassInfo c);
Maybe implementing such functionality somewhere as standart
function or method would be a a god

This function is basically the same as the cast function in
druntime. Look for _d_isbaseof in the file
dmd2/src/druntime/src/rt

Yes. I was thinking about this but I want some more "clear
looking" way of attaching handlers for errors, because I could
have a lot of them and using a lot of if operators is not good
for me.
Exception e = ...;
if(auto b = cast(BaseHTTPException) e) {
// use b of that type
} else if(auto
I suddenly posted unfinished message.
In my web application on D I want to implement some type of
"event based error handling". I'm process some events of request
handler with some wodified version of this:

The easiest way is to simply use cast:
Exception e = ...;
if(auto b = cast(BaseHTTPException) e) {
// use b of that type
} else if(auto s = cast(SpecializedHTTPException) e) {
// use s, e is of this type
}
and so on.
