I agree that dependent sequences of events, coordinated through a global are bad. But there are other usages which are not error prone. For example an allocation, logger, readonly settings, or a cache.

The burden is on the programmer adding a new thread to know what they can safely access. The conclusion of your argument looks like 2000s Java - throw a mutex on every property because you never know when it will need to be accessed on a th

I've recently found it helpful to think of problems at the scope of an individual process, rather than a set of functions in a library or framework. This makes it much clearer when a global variable makes sense or not, and generally wh

Why are singletons better? That's just a global object. > wrap a mutex What if my program has one thread? Or the threads have clearly defined responsibilities?
