--- Comment #14 from Pilar Latiesa <pilarlatiesa at gmail dot com> --- (In reply to Nathaniel Shead from comment #13) > Right; it's only an issue if we need to stream the body of the function > (i.e. if the function is a template, or marked 'inline'/'constexpr'/etc.) Ah, of course. I forgot that 'inline' is needed to make the body part of the module interface.
