Occam uses this model to delimit its blocks. It's a nice idea - no more
adding {/} around an if's "then" or "else" part simply because you've
changed it from one statement to two. Consistency like this can save a
lot of time looking for missing braces, etc. However, you do have to be
*very* careful with the space bar. One space in the wrong place can
also be a bit irritating to find, especially if you can't use vi/emacs
to match them for you like you can with {/}!

Couldn't you write a small(?) filter which would let you write C
without braces and fill them in for you from the indentation? It
doesn't seem too difficult. (No I'm not offering to do it).
