allow immutable state variables to be named in CAPS_SNAKE_CASE

This is more of a question than a bug report – IMO immutable variables should be allowed to be treated as constants, since they in fact cannot be changed.

Currently the code below returns a warning Variable name must be in mixedCase when linted with the recommended ruleset.

contract Test {
  uint16 public immutable TEST_MODE;
  constructor(uint16 _testMode) { TEST_MODE = _testMode; }
}

I don’t know what is the state of this issue now but having support for this would be great 👍

It’s hard to think of a good single setting here, since it really concerns two rules. The simplest way would be to have some “general config” option treat-immutable-vars-as-constants, but that’s kinda bad design since it’s not really a general option, just a two-rule option… Maybe it will be enough to add a treat-immutable-var-as-constant: true option to both these rules? You’d have to turn on both to have immutable variables linted in CAPS_SNAKE_CASE, and without them it would lint them in mixedCase.
