Elixir: using global operators in pipes
# To concat to lists, you normally do:
list = [1]
list ++ [2]
# result: [1, 2]
# How do you do that in pipelines?
# Global operators are under the Kernel module, so you can use them with the pipe operator.

Install Erlang for Elixir on OS X with working Observer to fix the wxe_driver.so not found error
- Download Erlang source from http://www.erlang.org/download.html
- tar zxvf otp_src_18.2.1.tar.gz
- Configure for 32 bits (wxe_driver.so won't be generated for 64-bits):
- CFLAGS=-O0 ./configure --disable-hipe --enable-smp-support --enable-threads --enable-kernel-poll
- ./otp_build autoconf
- ./configure && make && sudo make install
- which erl
- Install Elixir
- iex
- :observer.start should finally work

Sublime Text 2 Lua language file with support to stored functions. With it Go to Symbol captures all of the following scenarios: local stored; stored = function() end / local class = {}; local stored; class:stored = function() end / class.stored1 = function () end / local function loc(params) end / function glob(params) end
