The following functions (defined in the standard library but excluded if [`no_stdlib`]) operate on arrays:
| Function | Description |
| ---------- | ------------------------------------------------------------------------------------- |
| `push` | inserts an element at the end |
| `pop` | removes the last element and returns it ([`()`] if empty) |
| `shift` | removes the first element and returns it ([`()`] if empty) |
| `len` | returns the number of elements |
| `pad` | pads the array with an element until a specified length |
| `clear` | empties the array |
| `truncate` | cuts off the array at exactly a specified length (discarding all subsequent elements) |

| `push` | inserts an element at the end |
| `append` | concatenates the second array to the end of the first |

| `clear` | empties the object map |
| `mixin` | mixes in all the properties of the second object map to the first (values of properties with the same names replace the existing values) |
| `+` operator | merges the first object map with the second |
