If, by "It helps people avoid accidental...", you mean "at compile 
time", then it's not always detected in compile time, because the 
existence of a lock doesn't mean a mutex is locked (e.g. unique_lock). 
If you mean "at run time", then it can be checked without the lock being 
passed as a parameter to wait(). Either way, I see no need for passing it.
