AFAICT, `sexp-at-point` correctly finds the parenthesized thingy, but it
is asked to return the Lisp object it represents rather than a string,
so it `read`s, which inevitably obeys the ELisp syntax.
IOW, I suspect you want (thing-at-point 'sexp) rather than
(sexp-at-point).

I don't think it's a bug. forward-sexp moves across balanced
expressions, so it is not specific to Lisp. By contrast,
sexp-at-point is specific to Lisp and Lisp-like syntax, and so it uses
the buffer's syntax. Which is why ';' affects the result.

Hi,
I have this string expression in latex-mode:
$K(U_1, V_1, x_1; t_2, x_2)$
If the pointer is located on the opened "(" and I run "forward-sexp" it
works and the
pointer goes after the closed ")".
But if, again, the pointer is located on the opened "(" and I evaluate
"(sexp-at-point)" it returns nil.
If I remove the ";" symbol from the expression it works and returns the
sexp-at-point:
$K(U_1, V_1, x_1 t_2, x_2)$
Is it a bug?
Best regards,
Gabriele
