If we're going to use c++-mode as a reference, then, without
electric-pair-mode you get another class of "bigger" bugs.  Just type

emacs -Q thingy.cpp -f c++-ts-mode

int main () { RET for (;;) {printf("infloop"); RET }

it still bounces around.  c++-mode doesn't.  Sure, you may say
"oh that's because the c++-ts-mode indenting is off".  OK, then I say
"when/if it's ever fixed, then we can add these extra
electric-indent-chars".
