6.A: /, |, ! as there are in 2LC.
6.B: *, +, ? are non-counting
6.C: No DISTINCT
6.D: No {} forms: {n}, {n,m}, {n,}, {,m}
Option 6 also removes the {} forms.
+ Leaves the syntax open for the future
e.g. {*}, {?length}, {?length>5}
+ {n,} is currently defined depending on *
+ {n,m} for large m-n, has the similar computability issues (WM-1)
