+// TODO: need to come up with another syntax for bitfields, and use that syntax
+// for fixed-length arrays. the problem is, we cant use {} for those kinds of
+// arrays because they aren't pointers under the hood and that goes against the
+// arf design goals in a nasty ugly way, and not only that. but the :mut type
+// qualifier is meaningless on fixed length arrays now. the bit field syntax
+// solves both of these problems very gracefully. but now, the problem is coming
+// up with new bit field syntax. implementing this change is extremely
+// necessary, for it will supercharge the coherency of the language and make it
+// way more awesome.
+//
+// this new syntax cannot conflict with arguments, so it cannot have any
+// tokens that begin those. basically all symbol tokens are on the table here.
+// some ideas:
+//
+// ro member:Type ~ 4
+// ro member:Type & 4    <- i like this one because binary &. so intuitive.
+// ro member:Type % 4
+// ro member:Type | 4
+// ro member:Type ! 4
+// ro member:Type (4)    <- this looks phenomenal, but it needs new tokens not
+//                          used anywhere else, and it would be mildly annoying
