ENV lacks the following methods:

  clear, replace, update, shift, invert
  default_proc, default, defalt=

the latter three (deal default values) is meaningless.
"clear", "shift" and "update" are useless (in my opinion) but may be
harmless to have.

"replace" and "update" (they are aliases) are good to have.  I will
add them later.
