Yes, which I think is easier than having to parse and understand this identifier every time you see it.

Especially since after a few times you will remember what it means and not have to look it up anymore. There's a good reason we use jargon for complicated concepts rather than re-explaining them every time they're used. "while" is a lot easier to understand once its meaning has been explained to you than "EveryTimeWeGetHereCheckIfThisConditionIsTrueAndExecuteThisCodeBlockAndJumpBackHereIfSo".

Whereas with this English symbol that might not fit on a screen, there are none of those problems?! If the concept is foreign to you to begin with, but you have to care about it for some reason, you're going to have a bad time with either 1 or 2 no matter what the symbol is. (Though I agree that transliterating to BiaoJie would make it easier.)
