+<para>GHC can also read in External Core files as source; just give the <literal>.hcr</literal> file on

+A current infelicity is that you need to give teh <literal>-fglasgow-exts</literal> flag too, because
+ordinary Haskell 98, when translated to External Core, uses things like rank-2 types.</para>
