Hello dear community!

I've met a little issue. How can I generate struct or class 
copying some fields and methods from another struct or class? 
I've found methods to get fields. They are 
std.traits.FieldNameTuple and std.traits.FieldTypeTuple but I 
can't find a method allows getting methods from struct or class.

Other words I want to get fields and methods by string values and 
copy them to my struct. Is it possible? Or do I want something 
strange?

Thanks in advance. Sorry if my English is not clear.

You need a wrapper, but it would include all fields and methods from 
base struct/class and you just expose only that you need. So it's quite 
possible except I don't known how you can exclude needless fields.
But FieldNameTuple etc are not enough, your best friend is 
__traits(allMember, ...), iterating over its output and making decision 
what current symbol is and processing it according to its features. It's 
not trivial but not very complex.
