Re: [julia-users] Construction of a Matrix from columns via array comprehension

[Ethan Anderes]

I don't know mathematica but it looks like ... does the same thing. I use it 
often when I have a function that has a lot of arguments. 

function foo1(x,y,z,w)
        sin(x+y+z+w)
end

fin = [
        3,
        4,
        5,
        6
]

foo1(fin...)

It also works for keyword args 

function foo2(;x = 1, y = 2, z = 3, w = 4)
        sin(x+y+z+w)
end

fin = [
        :x => 3,
        :y => 4,
        :w => 5,
        :z =>6
]

foo2(;fin...)

Cool, right?
