> Array.isArray(require('_http_common').methods);
true

so no need to use util._extend()

The methods array is used inside the http parser guts. That's the reason it's cloned, because accidentally (or intentionally) modifying it is bound to break things. I would just leave it as it is.

But sorting makes a clone...

Nuh-uh. :-)

$ iojs -p 'var a = []; a === a.sort()'
true

Waaaaaaa is it because no sorting took place?

No, sort always sorts an array in place. .slice might be better than _extend, though.
