I was having problems figuring out why my tests were failing in WWW::Mechanize, so I pulled out Test::LongString, and look what it showed:
t/tick............NOK 5# Failed test (t/tick.t at line 39)
# got: "POST http://x/\x{0a}Content-Length: 21\x{0a}Content-"...
# length: 113
# expected: "POST http://x/\x{0a}Content-Length: 21 \x{0a}Content"...
# length: 114
# strings begin to differ at char 23
# Looks like you failed 1 tests of 5.
Oooh, an extra, invisible space! Thanks, Test::LongString! (and RafaÃÆël!)
Cool

I wrote it when I was dealing with large strings with lots of non-printable characters -- a custom binary serialization scheme. -- I've a to-do list for this module. Notably, improve diagnostics : print in the message the part where the strings begin to differ.
Boy, can I use this!

Turns out that there are subtle internal differences between 5.6.0 (where GraphViz::Data::Structure works) and 5.8.0 (where it doesn't, at all).
This will make is much easier to see where the emitted dot code is different. Thanks from me too.
