 | Operations allowed in call-chain | None allowed; typically used within another function, like a comparison (with syntactic sugar, this would appear on the right side of the comparison). The outer function or comparison dictates the operations allowed in the call-chain. |
-| Notes                            | Literals can be `int`s, `float`s, `string`s, `date`s or `timestamp`s, where `date`s use the format `yyyy-mm-dd` and `timestamp`s follow ISO 8601 format. Note that in general `string` is interchangeable with all other formats, except when used in a `property` chained to an `entity`. In this case, we recommend matching the data type of the entity property being targeted.                                             |
