Overview ¶
Package constforms exercises the const shapes a `swagger:enum` member can take beyond a plain literal — the shapes that are invisible to a reader working on literal syntax alone, and which the go-swagger#3412 investigation surfaced one after the other:
- `iota`, where only the first spec of the block carries a type and a value at all and every following spec inherits both implicitly;
- constant expressions and references to earlier members (`1 << 3`, `LevelLow * 2`);
- rune literals, whose constant is an integer (`'a'` is 97, not the three characters `'a'`);
- `true` / `false`, which are predeclared identifiers rather than literals — Go has no boolean literal token;
- raw and escaped strings, whose delimiters and escape sequences are part of the syntax, not of the value.
Values come from the type-checker, which has already evaluated every one of these exactly.

Constants ¶
const ForeignDay foreign.Weekday = 13
ForeignDay is declared HERE but typed with an imported type that happens to be called Weekday too. Membership is decided by type identity, not by name, so it is not a member of the enum above.

Package foreign declares a type sharing its name with an enum type of the parent package, so the membership test cannot be name-only.
