Consider simple file.rb:

```
puts File.exist?("C:/work/napa.net/gui/bin/script")

```

There exists directory C:/work/napa.net/gui/bin/script

With C-ruby:

[11:11:29 ~/irb\_test] ruby file.rb  
true

With IronRuby:

[11:11:35 ~/irb\_test] rbx file.rb  
false

This discrepancy (among others) currently breaks the nice utility
