digitalmars.D.bugs - [Issue 21141] New: No introspection access to a field's default value


          Issue ID: 21141
           Summary: No introspection access to a field's default value
           Product: D
           Version: D2
          Hardware: x86
                OS: Mac OS X
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: andrei erdani.com

Structs and classes should offer for introspection each field's default value.
That should be available as a string that can be mixed in. For void
initialization, the string would naturally be "void".

A simpler alternative would be to just offer an array of immutable bytes that
can be used to initialize the object. That is suboptimal because it does not
skip void-initialized fields.

This blocks https://github.com/dlang/druntime/pull/3174.
