Re: [boost] A PP trick to define a synchronized block java-like macro

Quoting John Bytheway <jbytheway+boost@gmail.com>:

if (bool stop_ = false) {} else for (VARS DECLARATION; !stop_; stop_ = true)

which I'd consider more readable (Thanks to BOOST_FOREACH for this trick).

The other trick in this part of the book is to use nested fors, which can give you slightly more flexibility. FOREACH does this too, IIRC.
