Subject: Dynamic message dispatch?

Suppose I have methods foo and bar.  How can I read a string from ARGV
or input and turn it directly into the message dispatch?  I'm trying
to avoid explicit if/else or switch based dispatching, so that the
logic wouldn't change if someone (me) later adds new methods directly,
by sub-classing, or using mix-ins.
