<p>
Lists are good for when we want a collection of one type, but sometimes we
want to combine multiple values of different types. In this case tuples are a
quick and convenient option.
</p>
<p>
The tuple access syntax can be used to get elements from a tuple without
pattern matching. <code>some_tuple.0</code> gets the first element,
<code>some_tuple.1</code> gets the second element, etc.
</p>
<p>
Tuples are generic types, they have type parameters for the types they
contain. <code>#(1, "Hi!")</code> has the type <code>#(Int, String)</code>,
and <code>#(1.4, 10, 48)</code> has the type <code>#(Float, Int, Int)</code>.
</p>
<p>
Tuples are most commonly used to return 2 or 3 values from a function. Other
times it is often is clearer to use a <em>custom type</em>, which we will
cover next.
