-<p>
- It's common to want to call a series of functions, passing the result of one
- to the next. With the regular function call syntax this can be a little
- difficult to read as you have to read the code from the inside out.
-</p>
-<p>
- Gleam's pipe operator <code>|></code> helps with this problem by allowing you
- to write code top-to-bottom.
-</p>
-<p>
- The pipe operator takes the result of the expression on its left and passes it
- as an argument to the function on its right.
-</p>
-<p>
- It will first check to see if the left-hand value could be used as the first
- argument to the call. For example, <code>a |> b(1, 2)</code> would become
- <code>b(a, 1, 2)</code>. If not, it falls back to calling the result of the
- right-hand side as a function, e.g., <code>b(1, 2)(a)</code>
-</p>
-<p>
- Gleam code is typically written with the "subject" of the function as the
- first argument, to make it easier to pipe. If you wish to pipe to a different
- position then a function capture can be used to insert the argument to the
- desired position.
