Re: is ||= threadsafe?

in reply to is ||= threadsafe?

What's more, it can't be implemented as thread safe, because the ||= operator must evaluate its rhs only if the lhs is false, and the expression on the rhs can have any side effect, including waiting a lot, so it would be bad to lock all other threads out during that time.
