More agressive `with` in Agda 2.4.3 [Re: [Agda] More aggressive `with`: Please check your Agda-2.4.2 developments!]

[Andreas Abel]

Thanks for all the replies I got so far!

It seems that many use Agda 2.4.3 (master development branch) already, 
so I merged my changes into a fork of the master branch.  Here are the 
installation instructions for 2.4.3+issue1692:

   git clone https://github.com/andreasabel/agda-issue-1692.git
   cd agda-issue-1692
   # by default, we are on the master branch in a fresh clone
   make install-bin

Cheers,
Andreas
