@mixin flex() throws no errors when passed space seperated values

[jeffkamo]

It's an easy mistake to accidentally type out...

@include flex(1 0 auto);

But that doesn't actually work, as the mixin expects three separate parameters that must be comma separated. Like...

@include flex(1, 0, auto);

Is there a way to make Sass throw an error when commas are forgotten?

I think I've got a fix for this. Do a check to see if $fg is a list and then, if it is, grab the first list item. I'll up a PR.

Thanks @kpeatt ! I was wondering for a sec why it wouldn't be possible just to use a single argument, but I see it's divided because the fallbacks only use the grow option. Fix has been merged. :)

Sorry... but I cant find the problem. I am getting:

Error: wrong number of arguments (3 for 1) for flex
@include flex(1, 0, auto);
