Hi Niklas,
Apart from this, HSE now also parses any unrecognized pragma in option (e.g. LANGUAGE), declaration (e.g. RULES) or expression (e.g. SCC) position, allowing user-customized pragmas. Unrecognized pragmas in other positions will (unfortunately) give a parse error. If this ever means a problem for you - let me know!
This is likely to be a problem for me :-) I certainly have OPTIONS_DERIVE and CATCH pragmas that I've inserted into various programs over time. I think failing on an unrecognised pragma is probably a bad idea, when ignoring a pragma is usually perfectly safe. Thanks Neil
