Babylon has a bug (I guess) with locations for classes where decorators are involved. Instead of the class starting at the first decorator, it starts at the beginning of the `class` keyword. By moving the location to the first comment, it solves --some-- of the issues with decorator comments.
* Verify parsers against same snapshot
- Reworked run_spec, now accepts 3th optional array argument for
additional parsers to verify against
- Merged duplicate run_spec configs
- Removed duplicate snapshot data
* Formatted run_spec.js with prettier
* Fixed node4 incompatibility
* Revert "Remove mutation in `printBinaryishExpressions` (#1067)"
This reverts commit e7312ad7b2.
* Revert "Make it clear what parser was used in each snapshot (#1068)"
This reverts commit 4f7ae4815b.
Mobx is the only popular JavaScript library that I know about which uses decorators. They put things on the same line so we should follow their conventions.
The logic implemented here is the following: if there is one decorator, it's on the same line. If there is more than one, they are each on their own line.
