Great catch! Thanks for reporting this. We may need to rethink field-less type extensions to solve for this ambiguity :/ |

I think allowing empty fields' blocks at parse time could work. |

Yeah, I think you're right. Requiring a fields block, but allowing the fields block to be empty might have to be the answer here, even though it's a bit inconsistent with other grammar rules in GraphQL :/ I'll do a bit of brainstorming with a few other folks and we'll resolve this quickly |

This replaces:
```graphql
type Foo implements Bar, Baz { field: Type }
```
With:
```graphql
type Foo implements Bar & Baz { field: Type }
```
With no changes to the common case of implementing a single interface.
This is more consistent with other trailing lists of values which either have an explicit separator (union members) or are prefixed with a sigil (directives). This avoids parse ambiguity in the case of an omitted field set, illustrated by #1166
This is a breaking change for existing uses of multiple inheritence. To allow for an adaptive migration, this adds a parse option to continue to support the existing experimental SDL: `parse(source, {legacySDL: true})`

After brainstorming came up with what I think is a more consistent solution, though it does constitute more of a breaking change from existing usage. See #1169 for a path forward along with suggested migration tools |

This is more consistent with other trailing lists of values which
either have an explicit separator (union members) or are prefixed
with a sigil (directives). This avoids parse ambiguity in the
case of an omitted field set, illustrated by
[github.com/graphql/graphql-js#1166](graphql/graphql-js#1166).
For now, the old method of declaration remains valid.

Extend without fields followed by extend makes second extend to be parsed as types to implement. Note that locations are faulty in test (cause it's hard to deduce them).
