Prune {{incorrect}} tags. Ada, Common Lisp and UNIX Shell are incorrect (because the function is not anonymous), but there seems to be no fix.

In Ada you can define functions local to other functions/procedures. This makes it invisible to outside and prevents namespace pollution.
Line 78 ⟶ 77:
=={{header|Common Lisp}}==
This puts a function in a local label. The function is not anonymous, but the name <tt>fib1</tt> is local and never pollutes the outside namespace.

(defun fib (number)

(if (< number 0)

Recursion is always anonymous in Forth, allowing it to be used in anonymous functions.

The shell does not have anonymous functions. Every function must have a name. However, one can create a subshell such that some function, which has a name in the subshell, is effectively anonymous to the parent shell.
