RickHull: Not a fan of the syntax, but it's effectively the same language.
I'm the weirdo who likes Erlang's syntax. I love Ruby's syntax as well, but I just don't think it fits the model.
It's absolutely not a mark against Elixir, by the way -- it's a fantastic language.
The main thing for me is that Ruby's syntax works well for Ruby, it feels right when I'm just coding in Ruby and it's fun to do, because the basic syntax is a lot of fun and you can do odd little metaprogramming things that help when you need a really weirdly shaped hammer.
Erlang's syntax can seem weird but it's very straight-forward to me -- Elixir has some things I'd love to see, like the pipe operator and stuff like fn(&1, 5) to create new functions (I haven't decided if this is actually currying), but I still like how much simpler Erlang's syntax is.
If you're doing sysadmin stuff, perl's usually present on more systems by default. Python as well. Assuming you don't have too much red tape about what's available on systems, though, that's not too hard to remedy.
I personally don't like them, but my learning method has always been beating my head against a wall. If you're not sure, give it a try, see if you feel like you actually understand anything in the process.
