This is an usage example, it isn't an use case.

Field-to-field conversion seems not natural, and it is called
'Structural conversion'.
I agree. We could, however, add std.conv.structuralCast.

I have written a simple conversion template for tuples, structs and classes:
https://gist.github.com/1299046
The problem is that it may conflict with to!Class1(Class2) template.
This template does dynamic cast and throw exception when the target is
null and source is non null. Why implement

This is only the part to complement universal range/array to
tuple/struct/class conversion. It may be useful in mapping runtime
fields like database rows or CSV lines onto objects. I think Phobos
