//! Operations on tuples
//!
//! To access a single element of a tuple one can use the following
//! methods:
//! To access a single element of a tuple one can use the `.0`
//! field access syntax.
//!
//! * `valN` - returns a value of _N_-th element
//! * `refN` - returns a reference to _N_-th element
//! * `mutN` - returns a mutable reference to _N_-th element
//!
//! Indexing starts from zero, so `val0` returns first value, `val1`
//! returns second value, and so on. In general, a tuple with _S_
//! elements provides aforementioned methods suffixed with numbers
//! from `0` to `S-1`. Traits which contain these methods are
//! implemented for tuples with up to 12 elements.
//! Indexing starts from zero, so `.0` returns first value, `.1`
//! returns second value, and so on. In general, a tuple with *N*
//! elements has field accessors from 0 to *N* - 1.
//!
//! If every type inside a tuple implements one of the following
//! traits, then a tuple itself also implements it.
