Feature #2509

Updated by Yutaka HARA about 3 years ago


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:

:type => 'application/octet-stream'.freeze,
:disposition => 'attachment'.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?
