Thanks for the kind words and the explanation. I do not feel very
confident about having a function that relies on a file scope setting
of lexical-binding, which as in this case happens 300 lines earlier.
Wouldn't it be better to have functions that work whatever the value
of lexical-binding, if possible?

If this alternative works whatever lexical-binding, it seems superior
to me. Isn't it?
