Make sure you have checked all steps below.

Prerequisite

• Please consider implementing the feature as a hook script or plugin as a first step.
  • pyenv has some powerful support for plugins and hook scripts. Please refer to [Authoring plugins]
    (https://github.com/pyenv/pyenv/wiki/Authoring-plugins) for details and try to implement it as a
    plugin if possible.
• Please consider contributing the patch upstream to rbenv,
  since we have borrowed most of the code from that project.
  • We occasionally import the changes from rbenv. In general, you can expect changes made in rbenv
    will be imported to pyenv too, eventually.
  • Generally speaking, we prefer not to make changes in the core in order to keep compatibility with
    rbenv.
• My PR addresses the following pyenv issue (if any)
  • Closes https://github.com/pyenv/pyenv/issues/XXXX
