Wouldn't it be better to only enable Haskell2010 and XmlSyntax and then rely on LANGUAGE pragmas? I guess optimally we want to add support for -Xoptions to hsx2hs but in the mean time…
BTW I think hsx2hs is in fact affected by these backwards-incompatible changes, and lacks an upper bound on its HSE dependency! Is hub.darcs.net the official location of the hsx2hs repository these days? On Tue, Aug 20, 2013 at 4:49 PM, Niklas Broberg <niklas.brob...@gmail.com>wrote: > HSE parses based on pragmas by default.
