As far as I know now, in GHC it could currently just be an alias for NOINLINE, but the GHC gurus could say for sure. Except it should require a monomorphic constant - otherwise the guarantee doesn't make sense. And it would have clear comments and documentation that state that it guarantees that the value will be computed at most once. That way, bugs could be filed against it if that ever turns out not to be true. Other applications and libraries that support the pragma - such as other compilers, and hs-plugins - would be required to respect the guarantee, and bugs could be filed against them if they don't.
