// This package is intended as a place to copy functions from the
// golang.org/x/exp package. Copying these functions allows us to rely on our
// own code instead of an external package that may change unpredictably in the
// future.
//
// It also prevents problems with transitive dependencies whereby a
// package that imports Task (and therefore our version of golang.org/x/exp)
// cannot import a different version of golang.org/x/exp.
//
// Finally, it serves as a place to track functions that may be able to be
// removed in the future if they are added to the standard library. This is also
// why this package is under the internal directory since these functions are
// not intended to be used outside of Task.
