I've got it! :) *AND*, I don't have to expand my thinking about
what's true and what's false in Ruby. What I have to keep in mind is
that hashes return a default value for an undefined key. Unless some
other value for the default was set at the time the hash was created,
the default value is nil. So, when no default value is explicitly set
at the time the hash is created, there is no real difference between:
if myHash[:akey]
and
if myHash.fetch(:akey,nil)
As I say, I think that I have it! :)
Thanks to all who contributed.
