I guess 2) seems more consistent, but I don't have much of an opinion.
Choosing one or the other of the parentheses seems a bit arbitrary.=20

Thanks for the explanation.

I didn't know how to answer, so I looked how other editors do. I found two
behaviors:

1. Unless the point is right by the parens, it should highlight the curly
braces. So in this case it would highlight the curly braces.

With the point in these places would highlight the parens, otherwise would
highlight the curly braces:

{|(|foobar}|)|

2. Ignore and don't highlight anything.

> How can I set emacs to show parens when the point is anywhere inside of them?

If you are comfortable with installing packages, "highlight parentheses"
(https://sr.ht/~tsdh/highlight-parentheses.el/) implements this.

That variable doc says "If non-nil, show parens when point is just
inside one.", so when point is right by the paren.

Anyway, I think it would make sense to add what you're requesting -- but
I'm not sure it would be efficient, or that it's well-defined.  For
instance, if you're in text-mode and the text is

  {(foo|bar})

what should it be blinking?

How can I set emacs to show parens when the point is anywhere inside of
them?

For example, with the point in the character "i": (po|int)

Coming from other editors, I expect that the parens are highlighted, but in
emacs they're only highlighted the point is on paren or immediately after
it, even with the variable "Show Paren When Point Inside Paren" set to "on".
