Exception handling discrepancies

Ruby IronRuby
1

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

These bugs are great. Are you reporting them on the RubyForge IronRuby
site? That way they won’t get lost in the mailing list archives.
