For example, expanding it to ``\x -> x \`g3a\` "hello"``. Historical note. Earlier versions of GHC allowed these now-rejected applications, by inserting -automatic eta-expansions, as described in Section 4.6 of `Practical type inference for arbitrary-aank types <https://www.microsoft.com/en-us/research/publication/practical-type-inference-for-arbitrary-rank-types/>`__, where it is +automatic eta-expansions, as described in Section 4.6 of `Practical type inference for arbitrary-rank types <https://www.microsoft.com/en-us/research/publication/practical-type-inference-for-arbitrary-rank-types/>`__, where it is called "deep skolemisation". But these automatic eta-expansions may silently change the semantics of the user's program, and deep skolemisation was removed from the language by |
