+|  2. | refactor number data types to allow non-power-of-2 bit widths, and also add different float types        |    50€   (~ 51$) |                     |
+|  3. | lower ints pass. asks backend for supported types. lower arbitary-width integers                         |   100€   (~103$) | depends on 2        |
