Ok so maybe rather than just my specific suggestions of contributing to the Wikibook and working on a MatlabToJulia.jl (or modernizing MatlabCompat.jl) is anyone interested in forming some sort of MATLAB/Julia users SIG which can do these sorts of things (including others’ probably better ideas than mine) in a coordinated way? This could just be a sub-forum here on Discourse (and, if people insist, a Slack channel, but ugh, Slack 
).
I think individually we probably are very busy and have little time but collectively we can do a lot to turn some of the kinds of discussion we have on threads like these into some concrete solutions that build on the (1.0) core language.
