51 | (* Not clear how to allow function declarations to specify a return type | |
52 | and how to allow both to be specified as static, because they are in | |
53 | different rules. The rules seem to have to be combined, which would allow | |
54 | functions to be declared as local variables *) | |

56 | (* Not clear how to let a function have a parameter of type void. At the | |
57 | moment, void is allowed to be the type of a variable, which is wrong, and a | |
