Auto-widest

https://tex.stackexchange.com/questions/29322/how-to-make-enumerate-items-align-at-left-margin

However, isn't there some way to make enumerate detect the width of its widest label automatically, instead of having to set it for each individual list? I feel like there must be some way, I just couldn't figure out how from the enumitem doc...
