Some formulas get very complex and I’d like to be able to add comments inline (just like you would by using `//` in javascript or `<!--` in html) to give context on why certain formula logic is done the way it is, or so you can quickly test different formulas without having to remove unused logic each time.

I know there’s already a description field, but that is for the entire formula and doesn’t provide the specific line-by-line context I’m sometimes looking for.

Hi,

I agree that comments inside formulas are very helpful, whether for complex, long formulas, or to just test/debug by disabling parts of it.

Unfortunately for the time being, before such a feature is implemented, I have had to resort to wasting a bit fo computing power to have at least single-line comments or to comment entire sections out.

I do **not recommend** it, unless it is absolutely needed, but you could **surround your comment with a LEFT or RIGHT** function with its secone argument set to 0. Of course, you would have to be careful with the **return type** of what you are commenting out, and possibly use **ToText** on it before passing it to LEFT or RIGHT.

**For instance, instead of comments like these, which are not supported:**

```auto
// This is a comment.
-- or --
/*
If(IsEmpty(SomeField),
  SomeFunction(SomeArg) +
  AnotherFunction(AnotherArg),
  "Already exists"
)
*/

```

**You would write:**

```auto
LEFT("This is a comment.",0)
-- or --
LEFT(
  If(IsEmpty(SomeField),
    SomeFunction(SomeArg) +
    AnotherFunction(AnotherArg),
    "Already exists"
  )
,0)

```

I would suggest adding some marker(s) and parentheses when needed, to distinguish comments from real LEFT/RIGHT functions, and make it easiler to see them visually, such as:

```auto
LEFT("COMMENT: This is a comment.",0)
-- or --
LEFT("COMMENTSTART:" +(
  If(IsEmpty(SomeField),
    SomeFunction(SomeArg) +
    AnotherFunction(AnotherArg),
    "Already exists"
  )
)+":COMMENTEND",0)

```

**Important:** It is wasteful, since it causes actual computing to comment somethign out, but when absolutely needed, or temporarily used for testing/debugging shoudl be fine.
