I love the Elixir syntax but worry it'd be like Scala: a better way for people who already know Java, rather than a way to use BEAM / OTP etc for people used to modern languages.
There are a handful of rules to remember, if that, and it's reasonably straight-forward. module:func becomes :module.func, the erlang func probably wants char lists rather than strings, atoms are lower-case and should be changed to :atom, vars are upper case and should probably be lowered.
Learning the Elixir language is easy, thinking functionally less so (for me at least).
Agree with rossj, there're some rules to remember and then it's not that hard.
