errors.Is compatibility

[alexedwards]

Do you know if there is any way to check for schema.MultiError using errors.Is()?

The following playground link demonstrates the problem I'm having:

https://play.golang.org/p/jwrz20goQqy

It's possible to check the error type using a type assertion, but that only remains possible if the error is never wrapped between being raised and the check.

The same thing seems to be true for schema.ConversionError and schema.UnknownKeyError.

Sorry, I was having a complete brain fart when I asked this -- it works fine when checking with errors.As() which is what I should have been using. See https://play.golang.org/p/_e8UmbXD1J- for working example.
