Implement a custom stringifier

The standards `CompositeStringifier` from "respect/stringifier" has lots
of interesting stringifiers. However, this library is not 100% focused
on engineers. Someone could type a string that matches a callable, and
then you will overexpose the system.

This commit makes sure that callables are not interpreted as callables.
