Rule Proposal: Explicit Boolean Precedence with Parentheses

[KamasamaK]

Incorrect use of order of operations is a pitfall I've seen a number of programmers fall into, and a linter would be perfect to suggest use of parentheses in those cases. This would not just be to prevent logic mistakes, but also clarify to anyone who does not have the order of precedence memorized. As such, I would expect this to be INFO or lower severity.

This would be triggered for expressions containing operators with mixed precedence-level without parentheses around sub-expressions.

Boolean operations

It should work for any conditionals such as those found in if, else if, while, for, <cfif>, <cfelseif>, cfloop.

Examples

foo OR bar AND xyz

Math operations

TODO?

For a start, look into combinations of and / or without ()
