This one jarred me as well.  tclsh has the property that undefined
commands are searched for on the user's PATH...
brains hgs 161 %> tclsh    
% ls
Enumeration.rb       index.html           take_two_procs.rb
Enumeration_test.rb  indexblob.rb         take_two_procs2.rb
attributes2.rb       nestedyields.rb      timed_read.rb
display_diffs.rb     partial_nesting.rb   udpclient.rb
docs_in_here_doc.rb  ruby-man-1.4         udpserver.rb
gnudecode.rb         self_print.rb
gnudecode2.rb        sort_lines.rb
% exit
brains hgs 162 %> 

but
 
irb(main):002:0> ls

I don't think we would want this to work like a shell straight out of the
box, but a "proper" ruby shell might be nice.
