I also have a template that gets the list of all members of an aggregate<br>
type (classes, structs and, well, modules, in a way), even the constructors,<br>
even the overloaded members, separated by type, and list them with their<br>
names and associated type. It even gets the types aliases and unittests,<br>
though I don't know what to do with the latter. That was part of a project<br>
to duplicate a type: generate a new type with this extracted info. I had<br>
vague projects to transform the methods into their const equivalent for<br>
example or to render the fields immutable, but didn't get that far. Would<br>
that be interesting to someone?<br>

I could imagine extracting the unittests could be useful for making a<br>
unittest system. Are they only included when passing -unittest?<br></blockquote><div><br>Hmm, don't know. Let see:<br><br>import std.stdio;<br><br>class C<br>{<br> int i;<br> unittest<br> {<br> assert(true);<br>
writeln("Hello World!");<br> }<br>}<br><br>void main() {<br><br> writeln([__traits(allMembers, C)]);<br> writeln(typeof(C.__unittest1()).stringof);<br> C.__unittest1();<br>}<br><br>No, compile this with and without -unittest, and __unittest1 is present. Oh, btw, contrary to the docs __traits(getOverloads, T) works also for structs and modules, not only classes.<br>
<br>The unittests type is void delegate(), which is coherent with them being blocks of instructions. You can even call it like a function (see the last line of main).<br>Strange, I never could get that to work... Maybe I didn't try this with a class.<br>
