| 4939 * * A literal string where any interpolated expression is a compile-time | |

| 4945 * * A constant constructor invocation. | |
| 4946 * * A constant list literal. | |
| 4947 * * A constant map literal. | |
| 4948 * * A simple or qualified identifier denoting a top-level function or a static | |

| 4952 * `e1 != e2` where `e1` and `e2` are constant expressions that evaluate to a | |
| 4953 * numeric, string or boolean value or to `null`. | |
| 4954 * * An expression of one of the forms `!e`, `e1 && e2` or `e1 || e2`, where | |
| 4955 * `e`, `e1` and `e2` are constant expressions that evaluate to a boolean | |
| 4956 * value or to `null`. | |
| 4957 * * An expression of one of the forms `~e`, `e1 ^ e2`, `e1 & e2`, `e1 | e2`, | |
| 4958 * `e1 >> e2` or `e1 << e2`, where `e`, `e1` and `e2` are constant expressions | |
| 4959 * that evaluate to an integer value or to `null`. | |
| 4960 * * An expression of one of the forms `-e`, `e1 + e2`, `e1 - e2`, `e1 * e2`, | |
| 4961 * `e1 / e2`, `e1 ~/ e2`, `e1 > e2`, `e1 < e2`, `e1 >= e2`, `e1 <= e2` or | |
