  By this time she had found her way into a tidy little room with
a table in the window, and on it (as she had hoped) a fan and two
or three pairs of tiny white kid gloves:  she took up the fan and
a pair of the gloves, and was just going to leave the room, when
her eye fell upon a little bottle that stood near the looking-
glass.  There was no label this time with the words `DRINK ME,'

Even so, Go provides a mechanism called GODEBUG to
reduce the impact such changes have on Go developers
using newer toolchains to compile old code.

A GODEBUG setting is a `key=value` pair
that controls the execution of certain parts of a Go program.
The environment variable `GODEBUG`
can hold a comma-separated list of these settings.
For example, if a Go program is running in an environment that contains

  /**
