+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
+ A4 #I2 *I
+}
