  I'm using with-idiom for managing external resources (90% of uses
of i/o channels, network connections, database connections), I find
it helpful.  With-function closes/frees resource when user-function
returns result or raises exception.
  A typical with-function can have a signature like:
val with_file_in_bin : string -> (in_channel -> 'a) -> 'a
  Of course, it's not safe in general case, since you can store
in_channel into some external reference or even return it, but I have
never made such mistakes (so far).
