The items listed below aren't errors - they're just "warnings". Perchance generates "warnings" when it detects code in your editor panel that looks like it may be a mistake, but which is technically not "erroneous" - that is, it's valid Perchance syntax, but it's "unusual" code and so might have been an accident on your part. Feel free to ignore these warnings if you know what you're doing! ꒰•ᴗ•꒱
