Is there any way I can have one handler for multiple exceptions?

I'm trying to do something like the following:

import std.exception;

class Foo : Exception
{
    this(string msg) { super(msg); }
}

class Bar : Exception
{
    this(string msg) { super(msg); }
}

void main()
{
    try
    {
    }
    catch (Foo) catch (Bar)
    {
    }
}

Some function might throw two types of exceptions, but I don't care
which one it is, I'd like to handle them both within one catch block.
Is this possible?

My use case is for the cmdln.interact library, I'm using userInput!()
to get an integer from the user and the function can throw either a
NoInputException or ConvException, but I don't really care which one
it is because if either exception is thrown my next action is to use a
predefined default.

Their base class is Exception, but catching all forms of Exceptions is
a bad idea.
