I think `default' and `key_missing' are to fix similar things, but
somewhat different.  They are corresponding to fetch(key,default) and
fetch(key){...} respectively.

But I think I'm not going with `key_missing'.  Hash look up
failure is more often comparing to method look up failure.
The performance penalty is not tolerable, I think.

Hash fall back by method 

I think 

  Hash.new{...}

is the way to go.
