table & multiple arguments

[paul@...]

>From the manual, I see a function can take indefinite number of
arguments by taking them from a table. But how about the reverse?

function foo(a, b, c)
    print(a, b, c)
end

Doing foo(1, 2, 3) works perfectly, but 

x = { 1, 2, 3 }
foo(x)

is an obvious error. How do I pass a flattened table as function
arguments? Is there any specific syntactical sugar for this? 

I know in Pike, you can do foo(@x), and foo(1, @y), etc.

Thanks in advance!
