Are you suggesting that convert should just do to and from strings? If
so, then combining it into one box seems unnecessary.
If you are suggesting it should do other things, then you are opening
a big box I don't want to go into. I do not want a unifying single
"convert" method, that turns anything into anything else, mainly
because it will gets things wrong most of the time.
