Hello,

I was just wondering if backtrace was supported yet with Exceptions.

In my code, I had this:  
rescue Exception =\> e

However, the backtrace is always nil.

puts e  
puts e.backtrace.nil?

Is this a known issue? Is there anyway to find out what is \ isn’t  
implemented yet?

trunk\tests\ironruby\Runtime\Exception spec’s don’t seem to cover  
backtrace.

Thanks

Ben
