New description:
The mime-types gem has a class and an instance interface. The class
interface uses an instance of itself. However, it doesn’t work in MacRuby.
It does not seem to be initialised properly. I have included in a sample
code with the expected behaviour. Changing `@__types__` to `@@__types__`
will not fix it.
{{{
#!/usr/bin/env macruby
class Test
def initialize()
@foo = true
end
def add(something)
puts "Is foo nil: #{@foo.nil?}"
end
@__types__ = self.new()
def self.add(something)
@__types__.add(something)
end
end
t = Test.new
t.add(3)
Test.add(4)
}}}
Output (MacRuby 0.5)
{{{
Is foo nil: false
Is foo nil: true
}}}
Expected (Ruby 1.9.1/1.8.7)
{{{
Is foo nil: false
Is foo nil: false
}}}
