Btw, aren’t there any ways of, at least locally, extending/redefining
such reader behavior such as the one of “'”, “,”/“,@”, “`”, “.”, “:”,
etc.?

For instance to experiment having such fancy and strange quotes in
source code: people really wanting to use it *might* want to use it as
such, instead of symbol component, which, inside ascii, often (with a
lot of exceptions such as in “!”, “?”, “:” (though it can have special
meaning) or “.” (though this one doesn’t work alone) other
non-human-text “punctuation” (also named “special characters”) such as
in “%&*+/<>address@hidden|”) cannot be part of a symbol without escaping (for
instance: “"#'(),;\[]`” (though this is tiny, it is not that simple)).
