Mash will cast all Hashes (and subclasses) to Mash on value assign
Reported by Carl Lerche | September 17th, 2008 @ 09:15 AM | in 0.9.8
Check the following bit of code:
class Magic < Hash ; end
(mash = Mash.new)[:magic] = Magic.new
mash[:magic].class == Mash
It seems that Mash is converting everything that it stores to Mashes (for the []= method and co.). It seems to me that values stored in a Mash should ONLY convert Hashes to Mashes on #update, #merge, etc... values stored in a Mash should not be modified.
This actually breaks sessions since any custom class inherited from Hash will get converted to a Mash (and obviously break everything.

I resolved the problem as follows: only pure Hashes (not subclasses of Hashes) will be converted to Mash on assignent.
