Extreme Example of TMTOWTDIby Cody Pendant (Prior)

I had a task to do in Perl yesterday, and it was a simple one.
I had a 25,000-word cracking dictionary file I downloaded, and I wanted to split it up by word length (My motivation is to do with cryptic crosswords).
I just wanted to put all the 10-letter words into a file called 10.words and so on.
So I wrote it the following very dumb way. I knew it was dumb, but I knew it would work.
And you've got to admit, it was quick to code.
Then, tortured by how dumb it was, I came back to the problem and figured something else out -- once I'd checked that I could have an array called "@1" and an array called "@2" and so on -- for a while I was convinced that was illegal, though I can't say why.
This is the better way:
Who wants to guess how much smarter the second was than the first?
The first way took 212 seconds (on a computer with a 333MHz chip) and the second took two seconds.
I just thought you might be interested, or have comments.
