          Issue ID: 16121
           Summary: the canonical way to create and use an exception type
                    is not documented on dlang.org
           Product: D
           Version: D2
          Hardware: All
               URL: http://dlang.org/
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: dlang.org

As a new D user I need basic information, for example if an exception should be
a class or struct, what class it should inherit from, and what is a good or
typical way to pass exception message in D. 
An example that I can easily spot and analyze would be by far the best way to
provide this.

I've been searching for this but could not find such example.
When I search for "dlang exception handling", the first page that google
redirects me to is:
https://dlang.org/spec/errors.html
It doesn't contain the needed info.
Then I tried to navigate manually to a page that should contain the
information. I landed on:
https://dlang.org/exception-safe.html
No luck there either.
