Compile error with base < 4.6 about heap HOT 2 CLOSED

Thank you for taking care of this.

I am a bit confused; I have no idea what an ‘install plan’ is and what needs to be done about the heap package now.

from heap.

@pruvisto the simplest way to address this, is to tighten the lower bound on base to base >= 4.6 in the Git repo (just so if you ever release a new version of heap to Hackage the meta-data is correct right-away) if you don't care to restore compatibility with base < 4.6.

What I mean by "install plan" is simply the result of the cabal solver when you "cabal install" something; it involves determining (solving for) the set of dependencies, flag settings etc in order to build a package including all required dependencies while satisfying the all declared version constraints.
