I wish that were possible! I use bracket-style resource allocation wherever I can, but in this case the Handle is the _result_ of a rather complex computation, so it has to leave the scope in which is was opened. A finalizer is all I can use.
It does not necessarily make bracket unavailable. Just put it somewhere outside, when it's known when the file will need to be closed. The whole action which opens the file inside it should be the "acquire" part of the bracket. Asynchronous exceptions will be blocked during executing it, so it should not be too long unless it unblocks them for longer parts. Of course there are also some cases when the file handle is deeply buried in some data structures, and we don't know when they will be freed. -- __("< Marcin Kowalczyk \__/ qrczak@knm.org.pl ^^ http://qrnik.knm.org.pl/~qrczak/
