For example, Rob Pike was quite unhappy to give up on Alef for Plan 9, and finally realized his ideas with Limbo.
So worshipping Plan 9 while ignoring Inferno is doing a disservice to their authors contribution to distributed computing platforms.
Interesting propaganda: http://9front.org/propaganda/
Along the way you can get a copy of Inferno from Vita Nuova to try stuff out.
For Go to be fully like Limbo, it needs to finish dynamic loading support.
I believe someone did some work but I’m having trouble finding it. Also they may have replaced Limbo with Lua (or maybe I just smoked too much of the good stuff).
