| === ALL USERS PLEASE NOTE ======================== CAR and CDR now return extra values. The function CAR now returns two values. Since it has to go to the trouble to figure out if the object is carcdr-able anyway, we figured you might as well get both halves at once. For example, the following code shows how to destructure a cons (SOME-CONS) into its two slots (THE-CAR and THE-CDR): (MULTIPLE-VALUE-BIND (THE-CAR THE-CDR) (CAR SOME-CONS) ...) For symmetry with CAR, CDR returns a second value which is the CAR of the object. In a related change, the functions MAKE-ARRAY and CONS have been fixed so they don't allocate any storage except on the stack. This should hopefully help people who don't like using the garbage collector because it cold boots the machine so often. | |
| Tyger, Tyger, burning bright Where the hammer? Where the chain? In the forests of the night, In what furnace was thy brain? What immortal hand or eye What the anvil? What dread grasp Dare frame thy fearful symmetry? Dare its deadly terrors clasp? Burnt in distant deeps or skies When the stars threw down their spears The cruel fire of thine eyes? And water'd heaven with their tears On what wings dare he aspire? Dare he laugh his work to see? What the hand dare seize the fire? Dare he who made the lamb make thee? And what shoulder & what art Tyger, Tyger, burning bright Could twist the sinews of they heart? In the forests of the night, And when thy heart began to beat What immortal hand or eye What dread hand & what dread feet Dare frame thy fearful symmetry? Could fetch it from the furnace deep And in thy horrid ribs dare steep In the well of sanguine woe? In what clay & in what mould Were thy eyes of fury roll'd? -- William Blake, "The Tyger" | |
