In defense of TFD, this isn't really a plausible comparison. A more likely
output from a test case would be:

...
  1) Failure!!!
test_my_var(TC_Example) [tc_example.rb:10]:
check for @my_var intialization
<nil> expected to not be nil
...

I do understand what you're saying. I've often wished for a "use strict;".
But it isn't worth regressing to Perl :-)
