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 H

HSE parses based on pragmas by default. This can be configured through the
ParseMode [1].
But your question regards HSP, Haskell Server Pages, which indeed just
enables most extensions by default. Right now there's no way to configure
that, but it shouldn't be hard for a skilled programmer to fix.
Good stuff!
Is there any way, or plans for a way, to parse a file based on its LANGUAGE
pragmas? Last I checked e.g. HSP simply enabled all extensions when
parsing, which can cause code to be parsed incorrectly in some cases.

Nice!
I hope that haskell-suite will eventually become awesome and solve most
of our automation-on-Haskell-code needs.
