// Use the same locale for test runs so that snapshots generated using code that

// uses Intl or toLocaleString() are consistent.

// We have to do this at this point instead of in the normal Jest setup hooks

// because ICU (and therefore Intl) only reads the environment once:

// specifically, at the point any Intl object is instantiated. Jest indirectly

// uses a locale-sensitive sort while setting up test suites _before_ invoking

// the setup hooks, so we have no opportunity to change $LANG outside of this

// ugly side effect. (This is especially evident when running tests in-band.)
