Macros

Enum	`Enum!( Type0, Type1, ..., TypeM )` denotes a predefined enum, the definition of which looks like:
def_impls	defines enums, with the syntax support of

enumx	tag an `fn` with `#[enumx]` to enable "type pattern matching" in `match` expressions that are tagged with `#[ty_pat]`/`#[ty_pat(gen_variants)]/`#[ty_pat(gen A,B,..)]`.
sum	collects all returned values in exit branches of the function, into an enum type, returning an `impl` trait
sum_err	To translate the `expr?` expressions in a different manner than the Rust's default:

Exchange	derives `enumx::Exchange` trait for custom defined `enum`s
FromVariant	Derives the trait `enumx::FromVariant` for user defined enum types.
Proto	Since `enum`s in Rust do not have prototypes, this macro derives them.
