Set whether we're in a pipeline in order to determine how to parse the
hash. The error message changes as a result, since the `hash` never
enters the block.
* babel/parser: test helpers: when test fails with an exception and both reference output file and options.json file do not exist, write a simple options.json with the error message to expect when such a file doesn't exist yet. This completes the `jest -u` capability for new tests which are expected to *fail*.
The extra field parenthesizedArgument was never set to true. It was
always set to false and the code that read this was incorrectly
checking if extra was present.
Fixes#7957

The proto modifier indicates that a property declared using `x: T` syntax is actually present on the prototype object of the class, rather than an own property.
The proto and static modifiers are mutually exclusive, as class declarations don't simultaneously define the static prototype object, as they do the instance prototype.
This syntax is only supported on declared classes, not object types, interfaces, or runtime class declarations, and as such should only appear in library definitions.
