Learn Ethereum smart contract programming

I hate immutable variables because I'm lazy but I would definitely use them as a feature in a system like this. Maybe I should reconsider using erlang or my position on immutble variables... Nope that's enough self discovery for today... Carry on.

Edit: And again erlang people can't take a joke. I'm literally making fun of myself for having an invalid bias and erlang folks take it as an attachment on the language.

It's also a commentary on how long it takes for devs to mind shift and incorporate new ideas.

There are two distinct features: immutability and single-assignment. Erlang is famous for single-assignment, and also happens to have largely immutable values, but they are not the same thing.

Immutability prevents things like in-place appending to an array, or in-place modification of a string.

Single-assigment means that the value bound to "someVariable" cannot be changed. E.g. `someVariable = new String("hello"); someVariable = new String("goodbye");` is illegal. But it still may be possible to mutate the value `someVariable.substitute("hello", "goodbye")` if the language allows mutation.
