Should String.prototype.split accept variable arguments optionally?

It's hard to add extra optional arguments to a long-standing built-in. 
People write code that passes an extra arg that has been ignored till 
the change; browsers that try shipping the new version then break that 
content, user blames browser (rightly so) but also the page, sometimes 
(not right).

Regexps suck away oxygen too, as others note. My suggestion is to focus 
fire for greater effect. If we need a new variable-split, we want a new API.
