The problem is that the "each" starts another statement (I don't know
if I'm using the right word), so another indentation level is added.
The solution would be to recognize "for each" as a group or something
similar.  I've come up with this hack that just decrements the indent:


(defvar le::for-each-regex
  "for\\(?:[ \t\n]\\)+each")

(defun le::for-each-intro-indent (langelem)
    (goto-char (cdr langelem))
    (if (looking-at for-each-regex)

(defun le::for-each-close-indent (langelem)
    (goto-char (cdr langelem))
    (if (looking-at for-each-regex)

(c-set-offset 'statement-block-intro 'le::for-each-intro-indent)
(c-set-offset 'block-close 'le::for-each-close-indent)


Add hook as appropriate for C++/CLI files.

Someone please still chime in with the "proper" solution.
