Subject: [ruby-core:46529] [ruby-trunk - Feature #6737] Add Hash#read and alias as #[].


Issue #6737 has been updated by trans (Thomas Sawyer).

Oh, thanks Shyouhei. That is very helpful breakdown. So I infer then, #[] (aka read) can be defined via #fetch as:

  def [](key)
    fetch(key, default, &default_proc)
  end

(And if so, save converting to C, this would be the first CRUDified method definition.)

Just, generally speaking it is nice to have a word named method for things when that suites readability better. Most operators (outside of numerical math, of course) have word equivalents. I actually hope you will accept this request based on this merit alone.

But more specifically this is also related to #6442, "CRUDifying" Hash's design. Adding #read is essentially the first step in doing this. Since #read, being the "R" in CRUD, would be one of the core methods, its preferable to have word-named method to go along with other methods, #store (for create and update) and #delete to act as that foundation.

Obviously there is nothing earth shattering here, just asking for an alias at this point. I'd like to incrementally submit requests/patches to "CRUDify" Hash rather then submit one huge patch as it will be much easier to test and ensure backward compatibility that way.
