184=item my $guard = cf::guard { BLOCK }
185
186Run the given callback when the guard object gets destroyed (useful for
187coroutine cancellations).
188
189You can call C<< ->cancel >> on the guard object to stop the block from
190being executed.

207
208Wait until the given lock is available. See cf::lock_acquire.
209
210=item my $lock = cf::lock_acquire $string
211
212Wait until the given lock is available and then acquires it and returns
213a guard object. If the guard object gets destroyed (goes out of scope,
214for example when the coroutine gets canceled), the lock is automatically
215returned.
216
217Lock names should begin with a unique identifier (for example, cf::map::find
218uses map_find and cf::map::load uses map_load).
