AFL block statement. Introduce a local instance of variable *current-speech-state*; set it to the instance of *current-speech-state* that was referenceable just before execution of the block; and execute body within this local scope. Within the block, all (free) occurrences of *current-speech-state* refer to the new local variable. Upon termination of the block, destroy local variable *current-speech-state* and reset the state of the underlying hardware to its pre-existing state. The AFL block also functions as a cobegin statement. A block terminates only after all events commenced within it have finished executing.
