Subject: [ruby-core:63182] [ruby-trunk - Feature #2509] Recursive freezing?

Issue #2509 has been updated by Alexey Muranov.


I have thought of the following solution: add simultaneously `Object#deep_freeze` and `Object#insulated?`.  If `obj.insulated?` is `false`, `obj.deep_freeze` (or `deep_freeze!` by the way?) should raise an error.

Feature #2509: Recursive freezing?

 I like freezing my constants, config files I read, etc... I believe it is the typical use case for #freeze.
 
 In all theses cases, what I really want to do is freeze everything. There is often no easy way to do this (e.g. for config files), or else one must explicitly call freeze a bunch of times, like:
 
 DEFAULT_SEND_FILE_OPTIONS = {
   :type         => 'application/octet-stream'.freeze,
   :disposition  => 'attachment'.freeze,
 }.freeze
 
 It would be very nice if there was an easy way to freeze recursively arrays, hashes, etc...
 
 A solution would be for #freeze to accept a level argument (similar to flatten, but the default being 1), or alternatively a boolean one (recursive = false). 
 
 Should I write a patch for this feature request?
 
 Thanks,
 
 Marc-Andr��
