Re^2: Copy hash's key to an array

Deak Monks,

Thank you very much every one. But is there any other efficient way besides keys and pushing individual keys. I am just being here a bit curious because itz perl and here there's always another way.

I'm sure there are other ways. You could treat the hash as an array, for instance, and use a loop to pull out all values with even-numbered indexes, starting with zero. But I doubt any other way could be as efficient as the built-in 'keys' function.	[reply]

I'm sure Perlmonks could find a few million silly ways to extract the keys from a hash without using the four character buildin called `keys`. But what's the point?	[reply] [d/l]
