strings, it produces a hash function and hash table in C or C++ code.  That
the hash function is perfect means that no collisions can exist and that
look-ups can be made by single string comparisons.")

other Haskell packages.

* gnu/packages/elm.scm (elm-compiler): Add a phase that updates the
Cabal file to allow for newer versions of 'ansi-terminal',
'containers', 'http-client', 'language-glsl', and 'network'.
[source]: Remove 'elm-compiler-relax-glsl-bound.patch'.
* gnu/packages/patches/elm-compiler-relax-glsl-bound.patch: Delete file.
* gnu/local.mk: Remove it.
