Yes, it's a good point that I neglected the poor Yada Yada operator! You prompted me to do what I should have done in the first place …. According to the all-knowing diff, aside from such obvious differences as one delta mentioning 5.10.1 where the other mentions 5.11.0, we have:

• Unicode interpretation of … redefined.
• Labels can't be keywords.
• length undef = undef and a grab-bag of other small, pleasant stuff (see lines 376–408 of perl5110delta).
• miniperl and internals stuff.
• Changes in parsing of #line.
• An extra method for tied filehandles.
• The \N escape (I could have sworn I saw it in the 5.10.1 delta, but it seems not!)
• Implicit strictures via use VERSION
• The all-important Yada Yada operator

Then I got too tired to read through all the module changes. :-)
