<https://forum.micropython.org/viewtopic.php?t=450>`_, and in `this issue thread
<https://github.com/micropython/micropython/issues/573>`_, provides some
optimizations that can be useful on smaller, memory constrained devices. However,
when using ``const()``, keep in mind these general guide lines:
- Always use via an import, ex: ``from micropython import const``
- Limit use to global (module level) variables only.
- If user will not need access to variable, prefix name with a leading
underscore, ex: ``_SOME_CONST``.
