Slightly modified but basically the same as your scenario, searching $a 
rather than $@ since it's not amenable to being set directly apparently.

irb(main):018:0> pp $0
"C:/mhiqTest/testAdoConnection.rb"
=> nil
irb(main):019:0> pp $a
["c:/ruby/lib/ruby/site_ruby/1.8/DBD/ADO/ADO.rb:57:in `connect'",
 "c:/ruby/lib/ruby/site_ruby/1.8/dbi.rb:424:in `connect'",
 "c:/ruby/lib/ruby/site_ruby/1.8/dbi.rb:215:in `connect'",
 "C:/mhiqTest/testAdoConnection.rb:16"]
=> nil
irb(main):020:0> $a.grep( %r/^#$0/ )
=> ["C:/mhiqTest/testAdoConnection.rb:16"]
