General method for new structure

[hendri54]

A convenient way of delegating methods is Lazy.jl @forward. But there are other approaches:

Method forwarding macro

MacroTools.jl defines a @forward macro but it’s in the examples folder. Lazy.jl exports its own version of the same macro but it’s not documented in the README. Come to think of it, while the @forward macro is quite useful, it isn’t really a macro development tool nor a functional programming tool. So I’m not too surprised that it is treated like a second-class citizen in those packages. Any thought about what kind of package would be a good fit for this?
