| 96 | | A general-purpose resizable array would need these attrs: |
| 97 | | * element_type (bit, int8, int16, int32, int64, int128, float32, float64, float128, string, pmc, any) |
| 98 | | * allocated_size |
| 99 | | * initialized_size |

| 101 | | * index_offset (used to make shift and unshift operate efficiently, not to allow arbitrary base indexing) |

| | 99 | A general-purpose resizable array would need these attrs: |
| | 100 | * element_size (corresponding to int8, int16, int32, int64, int128, float32, float64, float128, string, pmc & any) |
| | 101 | * allocated_size |
| | 102 | * initialized_size |

| | 104 | * index_offset (used to make shift and unshift operate efficiently, not to allow arbitrary base indexing) |
| | 105 | |
| | 106 | A general-purpose fixed-sized array would only need the element size and number of elements. |
