Comment (by dfeuer):

 I think thomie's version could be made a bit more intuitive using
 something like

 {{{
 runghc [runghc flags] module|filename [--ghc-flags [GHC flags]] [--
 [program args]]
 }}}

 For example

 {{{
 runghc Foo --ghc-flags -Wall -ddump-simpl -- -hi --bi
 }}}

 Like thomie's version, this requires the GHC flags to come after all
 runghc options and the module name, but it marks them out explicitly.
