\--verbosity:0 didn't help also, I don't wanna pipe / filter (not good to rely
on shell for that: error prone, can mess up with coloring, not cross platform)
ideally there'd be some extensible option, eg:
nim c
--disp_hints:Processing=false,SuccessX=false,XDeclaredButNotUsed=false,Link=false,Conf=false
- how to skip all the `Hint: foo [Processing]` during compilation? timothee
