Prior to this change, the lists of concepts were as follows:
lc x inlist my_list do
end
However, the syntax was strange for beginners, and so the Elixir team tried to find an alternative. Win syntax was
for x <- my_list do
end
Now the value has <-suddenly become context dependent. This is usually bad, but often more difficult to understand and allow for ambiguity, so they decided to change it.
send <- receive. , , .
, Process.send/3 . :noconnect :nosuspend. send (aka Kernel.send).
