what does it do?

how to turn the *scratch* buffer to lexical binding?

for the quick experiment, i evaluated this

   (setq lexical-binding t)

in the *scratch* buffer and it did what i wanted, namely allowed me to
use lexical binding by default for the purpose of the quick experiment.
i do not know how to switch the *scratch* buffer to lexical binding
otherwise.  without that, closures did not work as i needed.

normally, i write

   ;;; -*- lexical-binding: t -*-

at the beginning of a buffer.

does this do what i think it does, i.e. switch to lexical binding for
the entire buffer?
