Just had a thought (no idea how original) -- how about if fillStyle
were able to accept a 3 or 4 number array? eg. fillStyle = [0, 0.3,
0.6, 1.0] ?
That might work well if people are using arrays as vectors/colours

Philip Taylor suggested that a while back:

Ian Hickson replied only to the added value of returning an array
rather than a string:
http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2007-May/011268.html
(Which at this point is unfortunately no longer possible I'm afraid.)
Ah, I was not meaning to in any way suggest that we change the type of
fillStyle/strokeStyle, merely to overload the assignment behaviour to
allow arrays to be used -- although i'm not sure whether there is a
clean way to represent this in the idl definitions in the spec.
Basically i would expect
context.fillStyle = [1,1,1,0.5]
alert(context.fillStyle);
to produce an output akin to rgba(255,255,255,0.5) or some such.
The goal is simply to make a very common idiom (computed colours) be
much more concise. As I have said previously webkit also provides a
setFillColor(r,g,b,a) method which might be preferable? (the problem
with this kind of approach is that it means that there are two
distinct methods to set the active colour :-/ )
