PR06: Test the parsing on invocation number constraints.
Trip the parser so we don't get past it.
@>
1. Test with no zero and no many.
@$@<Sloth@>@{No zero and no many in this macro@}
2. Test with a zero.
@$@<Sloth zero@>@Z@{Can be called from 0 to 1 times.@}
3. Test with a many.
@$@<Sloth many@>@M@{Can be called from 1 to infinity times.@}
4. Test with a zero and a many.
@$@<Sloth zeromany@>@Z@M@{Can be called from 0 to infinity times.@}
5. Test with a zero and a many but out of order (should give error).
@$@<Sloth manyzero@>@M@Z@{Oops.@}
@A@<Error recovery point@>
6. Test with syntactic errors.
@$@<Sloth a@> @M @Z @{Oops.@}
@A@<Error recovery point@>
@$@<Sloth b@>@Z@Z@{Oops.@}
@A@<Error recovery point@>
@$@<Sloth c@Z@>@{Oops.@}
@A@<Error recovery point@>
@$@<Sloth d@>Z@{Oops.@}
@A@<Error recovery point@>
@$@<Sloth d@>@ZM@{Oops.@}
