I know is possible to create an object from its name. It's possible to

Would something like the following be possible?
string classname, methodname;
// Ask the user for class and method.
auto obj = Object.factory(classname);
invoke(methodname, obj, param1, param2);
Thanks
As far as I'm aware there is no way to do this in any of the standard
libraries. This said, it is possible (at least to some extent), to do
some runtime reflection by parsing symbols out of the object file and
demangling them - this is what I'm using, but it's not as extensive as
what you're requesting, it's very use specific (mainly missing calling
methods with any number of parameters). It should be possible with some
work though.
Another possibility would be to using __traits with some allMembers,
collecting all the names and a delegate in a hash and store it in the
object.
If it's possible to do this, you should, it's what I'd be using if I had
access to it, unfortunately, there's no such love for D1.
AFAIK, D2's TypeInfo and friends do have an interface for runtime
reflection (methods offTi() and getMembers()), though a quick glance
shows they're not implemented, i.e. return null all the time.
