Isn't the case here that, when GHC attempts to compile a plugin, it shouldn't use the `-fplugin` arguments for the compilation? Simple stage restriction: you can't use a plugin on itself.
That's true, but I'm not quite sure what you're suggesting: do you mean that GHC should silently ignore the `-fplugin` argument when compiling the plugin itself (and its dependencies)? I guess that would be more convenient in this case, although I imagine it would be counterintuitive in other cases (e.g. if you were trying to use a plugin on a module without realising the plugin depended on that module). Perhaps those other cases are sufficiently obscure that it is worth doing, and could perhaps be combined with turning on `-dynamic` automatically. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10077#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
