-# NOTES on the Implicit Intersection operator: @
-
- Sometimes we obtain a range where we expected a single argument. This can happen:
-
- * As an argument of a function, eg: `SIN(A1:A5)`
- * As the result of a computation of a formula `=A1:A5`
-
- In previous versions of the Friendly Giant the spreadsheet engine would perform an operation called _implicit intersection_
- that tries to find a single cell within the range. It works by picking a cell in the range that is the same row or the same column
- as the cell. If there is just one we return that otherwise we return the `#REF!` error.
-
- Examples:
-
- * Siting on `C3` the formula `=D1:D5` will return `D3`
- * Sitting on `C3` the formula `=D:D` will return `D3`
- * Sitting on `C3` the formula `=A1:A7` will return `A3`
- * Sitting on `C3` the formula `=A5:A8` will return `#REF!`
- * Sitting on `C3` the formula `D1:G7` will return `#REF!`
-
- Today's version of the engine will result in a dynamic array spilling the result through several cells.
- To force the old behaviour we can use the _implicit intersection operator_: @
-
- * `=@A1:A7` or `=SIN(@A1:A7)
-
- When parsing formulas that come form old workbooks this is done automatically.
- We call this version of the II operator the _automatic_ II operator.
-
- We can also insert the II operator in places where before was impossible:
-
- * `=SUM(@A1:A7)`
-
- This formulas will not be compatible with old versions of the engine. The FG will stringify this as `=SUM(_xlfn.SIMPLE(A1:A7))`.
- */

-/// Transverses the formula tree adding the implicit intersection operator in all arguments of functions that
-/// expect a scalar but get a range.
-///  * A:A => @A:A
-///  * SIN(A1:D1) => SIN(@A1:D1)
-///
