This plugin provides the programmer with a way to annotate certain types using a Fuse pragma from the fusion-plugin-types package. The programmer would annotate the types that are to be eliminated by fusion. During the simplifier phase the plugin goes through the relevant bindings and if one of these types are found inside a binding then that binding is marked to be inlined irrespective of the size. This plugin was primarily motivated by streamly but it can be used in general.
