CopyCorresponding(to, from): Move field values between structs with fields of same name and type

[WillianBR]

I find your project a very powerful feature which should be default into GO Lang.

There's one feature which could be implemented and make others life a lot easy. In the past the PC COBOL had a feature called "MOVE CORRESPONDING ...". Which was used to move values between structres fields with the same name. Ignoring the not corresponding.

I guess your package could implement it. Allowing to move field values between structs with fields of same name and type.

Anyway, thank you for your work.

I think, what you want could be achieved with something like:

bytes, err := <json/or any other marshaller>.Unmarshal(inStruct)
err := <json/or any other marshaller>.Marshal(bytes, &outStruct)

Note, this library recurses through a struct-tree of a single value and uses reflection to get defaults of the current struct, i.e. what to write to the fields is locally available, i.e. it doesn't passes any additional state.

What you suggesting, would require either passing the state, i.e. to know at which depth we are now and what path we are currently processing and/or recursing through two values at once.

In both cases, it's basically rewriting of the library.

btw, what you need is there already, see https://github.com/jinzhu/copier

@creasty I think, this one can be closed.
