Hi there,

today I updated my MacRuby installation from MacRuby 0.5b1 to 0.5 final. Sadly, this broke my class "MERStandard" which used a Set.
My Cocoa app embeds the MacRuby.framework. I initialized an empty set like this, which worked fine with MacRuby 0.5b1

mySet = Set.new

With MacRuby 0.5 final I am getting the following error:

An exception occured: NameError uninitialized constant MERStandard::Set

If I put a

require 'set'

at the top of my class file, I get the following error:

An exception occured: LoadError no such file to load -- set

Am I doing something wrong or was anything substantial changed in the relase version?

In the final 0.5 release we decided to revert our NSSet-based implementation of set and use the pure-Ruby implementation, so you do need to require 'set'. If 'set' can't be found in your application bundle maybe it's because you did not embed the standard library?
