Nesting should work for more than one level about dry-validation

As discussed, this won't work, for generating rules programmatically you can use the rule ast and built-in compiler (info in the README).

FYI a block in the dsl must return last rule, because we're and-ing it with the outter rule. so every time you call invoice_address.key it adds new rule to invoice_address which may accumulate more than one rule, and if that block doesn't return a rule then we don't know what to and-with :) each returns that symbol array, so it can't work because that's what to whole block returns.

One more thing - we can come up with various interfaces to remove duplication. ie invoice_address.filled?(:street, :zip, :country) etc. Ideas welcome.

Yeah, sorry. Forgot to close this! I'm totally with you on why my code does not work.
