+/// Creates a EnumSet literal, which can be used in const contexts.
+///
+/// The syntax used is `enum_set!(Type::A | Type::B | Type::C)`. Each variant must be of the same
+/// type, or a error will occur at compile-time.
+///
+/// This macro accepts trailing `|`s to allow easier use in other macros.
+///
+/// # Examples
+///
+/// ```rust
+/// # use enumset::*;
+/// # #[derive(EnumSetType, Debug)] enum Enum { A, B, C }
+/// const CONST_SET: EnumSet<Enum> = enum_set!(Enum::A | Enum::B);
+/// assert_eq!(CONST_SET, Enum::A | Enum::B);
+/// ```
+///
+/// This macro is strongly typed. For example, the following will not compile:
+///
+/// ```compile_fail
+/// # use enumset::*;
+/// # #[derive(EnumSetType, Debug)] enum Enum { A, B, C }
+/// # #[derive(EnumSetType, Debug)] enum Enum2 { A, B, C }
+/// let type_error = enum_set!(Enum::A | Enum2::B);
+/// ```
