Depends on #3044

  • Defines a GraphQLSchemaElement base class which defines a .coordinate property and toString/toJSON methods.
  • Adds base class to types, fields, arguments, input fields, enum values, and directives.
  • Uses this in validation error printing string templates.

Results in a net-reduction of code, minor simplification of definition.ts, and simplification/standardization of error messages

I've read over this and tried to understand what's going on. Adding the GraphQLSchemaElement base class, and having everything be a class that inherits it makes a lot of sense. I think all the elements are covered here.

Looks great to me! (But I'm still getting up to speed on this codebase)

I have no issue with switching the couple of schema interfaces to concrete classes, but if something would go wrong with this diff that's where I'd anticipate downstream issues.

oooh this is a much nicer pattern too. Quite clever, that the arg will be schematized when it's stringified.

oh that is a much cleaner pattern: it's great that we can now remove the only-needed-for-the-message value.

This change seems likely to break implementations that implement GraphQLInputField in a custom way. I don't know how common that is, but definitely not a purely safe adjustment.

Should this be Field ${fieldDef} is deprecated. similar to what you're doing in ValuesOfCorrectTypeRule?
