  4. def apply[A](default: A): UIO[IOLocal[A]]

    Builds a IOLocal reference with the given default.

    Builds a IOLocal reference with the given default.

    IO returned by this operation produces a new IOLocal each time it is evaluated. To share a state between multiple consumers, pass IOLocal values around as plain parameters, instead of keeping shared state.

    Another possibility is to use IO.memoize, but note that this breaks referential transparency and can be problematic for example in terms of enabled IO.Options, which don't survive the memoization process.

    default

    is a value that gets returned in case the local was never updated (with write) or in case it was cleared (with IOLocal.clear)
