check-paren like functionality

[rgemulla]

It would be great if smartparen could provide the functionality of Emacs check-paren command (which is unware of the paren pairs defined by smartparen).

[Fuco1]

Something like this should theoretically work

(defun sp-check-parens ()
  (interactive)
  (goto-char (point-min))
  (while (sp-forward-sexp))
  (sp-skip-forward-to-symbol))

unless there are of course bugs in the parser (there are some issues in comments... which we should probably eagerly skip instead of trying to walk them).

[rgemulla]

Yes, that's a already helpful!

It seems to move overly aggressively, though: Nested mismatched parens are not found, e.g., it will accept (}).
