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

                        -Dgpg.passphrase="<passphrase>" -Dgpg.keyname="<your key ID>"
                        In order to create the key pair, use the command "gpg &ndash;&ndash;gen-key".
                        (&ndash;&ndash; stands for double dash)
