RE: RE: Adding 2 + 2

[Adam]

perl -wle 'print $^W*2**$^W*2'

That's not 2 + 2, thats 2 squared.
(Ok, I know... the answer is the same... but the route is different.)

Well, speaking as a engineer by training, the program meets spec... where's the problem? <G>

If you wanted flexibility and easy upgrades, you should have made sure that was part of the original program spec.

Uh, I thought 2 squared was just a shorthand for 2 + 2, er, or inherently linked or something. Sure, it a ... what's that word, pathological? case but ...

So nearly...

2² is a shorthand for 2x2, which is a special case, since the exponent equals the mantissa. It's only equal to 2+2 by coincidence, though, or rather, due to the fact that 2 enumerates the number of arguments taken by binary (!=base 2) addition. There's nothing terribly pathological about any of this. The result (which I understand Larry wants allowed by Perl 6) that 0⁰=1 is really pathological.

And I may be just a novice, but how about:
 sub addtwoandtwo { 2+2 } ?

Thanks for the downvotes! Feel like telling me what's wrong?
