From the *scratch* buffer in emacs -q, type:
(setq-local lexical-binding t) M-x eval-buffer RET
Afterwards, M-: lexical-binding RET shows "nil", but I expect to see
"t".
If you instead type C-M-x in *scratch*, then M-: lexical-binding RET
does show "t".
For recent discussion also see Bug#30078, which is about turning on
lexical-binding in M-: (eval-expression) -- a different but related
issue.

This is how eval-buffer is meant to work -- it'll ignore any setting of
lexical-binding and just looks for
-*- lexical-binding: t -*-
cookies and uses that instead. This wasn't documented, though, but that
has been fixed on the trunk now.
