| /// A declaration is private iff its name is private, otherwise it is public. |
| /// A name q is private iff any one of the identifiers that comprise q is |
| /// private, otherwise it is public. |
| /// An identifier is private iff it begins with an underscore (the _ character) |
| /// otherwise it is public. |
| /// A declaration m is accessible to library L if m is declared in L or if m is |
| /// public. |
| /// @description Checks that label names can begin with an underscore and are |
| /// still usable. |
