Comment (by gracjan):

 Well, my skin is thick enough for internet discussions.

 I'd rather note as fact that cycles are burnt by this in multiple places
 like emacs/vim/atom/vscode and hie/ghc-mod/intero, those could be burnt in
 one place.

 Second I think this is a very important issue to talk about and I see
 pretty big benefit-per-char-of-discussion. Note that there were compilers
 that boasting by readability of their output (clang), quickly followed by
 their direct competition (gcc) and now high level of attention to compiler
 output is an industry standard (see Elm or Rust). I'd like to thank hsyl20
 for actually doing something about usability of compiler output.

 Third, I think ghc is just breaking expectations here. Just try to load
 Ruby, Python or C with the following code and see how much you expect:

 {{{
 require A
 require B
 require C
 }}}

 {{{
 from A import *
 from B import *
 from C import *
 }}}

 {{{
 #include <a.h>
 #include <b.h>
 #include <c.h>
 }}}

 There will be no output from these, unless you request extra verbosity to
 trace this functionality. GHC is an outlier.
