I see the same thing. I also note that `eval-region' produces the
same result as `eval-defun'. (I'd only tested `eval-buffer' initially,
and that respects the `lexical-binding' setting.)
My main point was that I'm dubious that enable-local-variables should
be allowed to affect lexical-binding in any situation.
While it's strictly true that the lexical-binding implementation
utilises a file-local variable, I feel like this particular variable
should be guaranteed to be respected when set, because it fundamentally
changes how the code will be interpreted.
Are there are any other file-local variables in that same category?
I couldn't think of any offhand, and so this seemed worthy of having
an exception made.
