-----------------------------------------+----------------------------------
When compiling code with a ghc plugin, e.g. '''ghc -O -fplugin SomePlugin
Main.hs''', recompilation is triggered for every module. This can make
plugins difficult to use in environments with many modules shared between
executables.
Since a plugin is a GHC library, I would like to propose that plugin
arguments and interface hashes be included in the dependencies for
compiled modules, in a similar way to how compiler flags are already
included. This would enable ghc to avoid recompilation of modules when
using plugins, provided that the plugin and plugin options haven't
changed.
