It's wrong if you try to read it as "move 0 into esp" because the source and destination are reversed in code from how it's expressed in English. The way to fix

It's wrong if you try to read it as "move 0 into esp" because the source and destination are reversed in code from how it's expressed in English. The way to fix that is to use the other syntax, or change how you think of the English. If read like Lisp, then it's "set esp to 0" and 'mov' is just a poor mnemonic.
