A cute idea, but also a modern accretion. Early C didn't have it
and as much as people like to say comparing a char to it's numeric
value is not a good idea it was quite common at one time.  I know,
because I was the one tasked with porting some of this code to
Primix where the chars all had a different numeric value.  I don't
know why they did it, but they did.
