+Execute shell builtins.
+
+Execute SHELL-BUILTIN with arguments ARGs without performing command
+lookup.  This is useful when you wish to reimplement a shell builtin
+as a shell function, but need to execute the builtin within the function.
+
+Exit Status:
+Returns the exit status of SHELL-BUILTIN, or false if SHELL-BUILTIN is
+not a shell builtin.
