Everything in bruijn is a function (including strings and numbers), so even <syntaxhighlight lang="bruijn">main [0]</syntaxhighlight> would be a valid solution since the argument of <code>main</code> is already a functional encoding of stdin.
A more obvious example:
<syntaxhighlight lang="bruijn">
first [0 [[0]]]
second [first [[1]]]
:test (second) ([[[[0]]]])
</syntaxhighlight>

It can also take a pure symbol, in order to retrrieve a symbolic result:
