For example, a user asks "I'm trying to solve this threading problem but I don't want to use lock() or interlocked.increment and I want a one line solution".
It seems like this isn't going to be helpful to anyone else and is therefore "unlikely to ever help any future visitors" and would thus be appropriate to be closed as "too localized".
Right?
More generally the constraints a user adds to a question have artificially ruled out most or perhaps all sensible answers that would work to solve the underlying need. Clearly in the limit the question becomes absurd "I want to assign 5 to 'i' without using an 'int'" but at what point does a question become worth closing vs worth closing?
