If the
includeReferencedFunctions property
is set to YES, the program namespace automatically includes all stand-alone
functions (functions declared outside of a program or library) that
can be found in its part lookup scope. That scope finds any of the
following stand-alone functions:
- Those located in the same file
- Those named in import statements
- Those in packages named in import statements
The default is NO. Stand-alone functions are not recommended for
new development.
