[nem-en] Emacs nemerle mode hang

[Snaury]

Hi everyone,

Is it only me who has this problem? I occasionally discovered that
when I start typing a new file:

def somefunc()
{
  def anotherfunc()
  <when I press { here emacs just hangs!>

This problem does not happen if I close the first level brace. And the
problem does not happen if second opening brace is not already
indented (if I start typing opening brace on column 1 it just jumps to
correct place and does not cause hang). Even like this:

{
  <pressing { hangs>

It hangs. I never encountered anything like this in other modes, and
my knowledge of emacs is just to little to even understand why it
might be happening. Any ideas why it could and a fix? (if it's not
only me or emacs bug)
