I'd rather have a class or instance level method that let me define this
behavior globally for all hashes, or locally for instances.  That way I
can keep the standard aref syntax, e.g. arg[:key] instead of using a
separate method name.  I wouldn't mind a way to ignore case, either.

h = {'foo', 1, 'BAR', 2}
h.symbol_alias = true    # or whatever
h.ignore_key_case = true # or whatever

h['foo'] # 1
h[:foo]  # 1
h["FOO"] # 1
h['bar'] # 2
... etc, etc.

That being said, I'll take a Hash#getopt method over nothing. :)

Dan
