While I appreciate guest languages for bringing new ideas to specific language platforms, at the end of the day I rather use those that are developed alonside the platform, hence Erlang instead of Elixir, at least if I would be ever doing something with it again.
Last time I touched Erlang, "Learn you some Erlang for great good!" was fresh out of the printers.
I loved Erlang. I want to use it, those who can master mnesia natively are a powerful wizard/ess. I've only touched the surface and seen it's raw power.
I've just not had time to learn further. As swapping between languages when trying to complete my original Tcl project is tricky. I'm now poking around with Crystal.
A rookie example of erlang and converting strings to base16. I posted in haste a while ago on Tcl's IRC but fun. Never did implement the teddy bear colour.
