This module defines a type for mutable, string-valued labels. Labels are variable values and can be used to track e.g. the command line arguments or other free-form values. All operations on labels are thread-safe.
N.B. This module exists to maintain backwards compatibility with
older versions of this library. New code should use the
System.Metrics.Label
module from the ekg-core package instead.
