Yeah, one of the things that still needs to be improved.
When using an int it could just use switch instead of looping to find
the match in config[].
Also note that it's put on the stack, it should be static.
If needed at all, possibly using #define.
So, if someone wants to work on this, please write a test, verify that
the test passes, then change to code to a more efficient version.
