Subject: bug#71777: 29.4; sexp-at-point in latex-mode when sexp contains ";"
Date: Tue, 25 Jun 2024 19:53:59 +0200

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
