[Ironruby-core] Exception handling discrepancies

[Robert Brotherus]

Consider following simple program exceptions.rb:
 
begin
    a = ABC
rescue
    puts "We have exception: " + $!
end
 
cruby can treat the exception as string, but rbx fails:
 
[11:24:38 ~/irb_test] ruby exceptions.rb 
We have exception: uninitialized constant ABC

[11:25:10 ~/irb_test] rbx exceptions.rb 
Snippets:0:in `main': undefined local variable or method `to_str' for
uninitialized constant Object::ABC:NameError (NoMethodError)
        from Snippets:0:in `Initialize'[11:25:16 ~/irb_test] 

The problem can be circumvented currently with to_s:
 
puts "We have exception: " + $!.to_s
