(5) Zero Parameter Functions
When an ifunction derived type is defined with zero number of
parameters, there are two calling conventions within expressions that
are allowed. For a function named 'foo' with zero input parameters the
calling styles are as follows:
When either an ifunction or ivararg_function derived type is defined
with zero number of parameters, there are two calling conventions
within expressions that are allowed. For a function named 'foo' with
zero input parameters the calling styles are as follows:
(1) x + sin(foo()- 2) / y
(2) x + sin(foo - 2) / y
