[MacRuby-devel] NSSet and Set broken in MacRuby 0.5 final?

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? Thanks and cheers Frank
