± Fantasai and I spent the day reviewing the syntax of all the functions currently 
± defined in CSS, per ACTION-413.  We posted our results and recommendations on the wiki 
± at <http://wiki.csswg.org/ideas/functional-notation>.  They are reproduced below:

You don't mention 'flex()'. Are you two in agreement it doesn't need to be a function, or are you OK with it either way (if it lives, the syntax is good)?

Also, while you have fresh memories of this broad review, can you comment on two concerns I had with flex():

	1) Are there precedents for functions that are not always applicable where they are defined (such as "width:flex()" when not in flexbox)?
	2) Are there other places where use of a function changes defaults (such as "width:flex(1)" implies "width:0" instead of "width:auto")?


I am not starting another discussion on flex() here, we'll have it at F2F, I am just interested if we have principles or precedents to compare...
