+description: Test of nested expansion and refusing macro without arguments
+comments: f(2) will expand to 2*g, which will expand to 2*f, and in this
+          moment f will not be expanded because the macro definition is
+          a function alike macro, and in this case there is no arguments.
+output:

+A4	I	f
