If I have an existing file with lexical-binding = nil, and I want to
add more functions to that file, what is then the preferred way to do
it? Should I write the new function with lexical-binding = t? Isn't
it risky or wrong to set lexical-binding at the top of the file (like
face-remap.el does), what would happen to the other functions, which
earlier had lexical-binding = nil?
Is there a way (and is it better) to set lexical-binding = t locally
for the new function?
Or is it better to make the new function work with lexical-binding =
nil, despite the caveats described by Pascal?
