Expanding array as function arguments

[Witold Rugowski]

Hi!
I wonder if it is possible to expand array as function arguments. Like

def foo( a, b, c)
end

foo [1,2,3].to_args


Is possible to do it?

Is possible to do it?

foo *[1,2,3]

(
similar to grouping several arguments into an array if method definition:

def foo(*args)
end

foo 1, 2, 3
)

How about foo *[1, 2, 3] ? (Note the "*" -"splat").

foo *[1,2,3]

end

foo 1, 2, 3
)

Thnx a lot

A note on splat; it can be used to both gather and unpack elements,
depending on the context. For example...

def baz(a, b, c)
p a, b, c
end
def foo(*bar) # gathering - bar = [1, 2, 3]
baz(*bar) # unpacking - bar = 1, 2, 3
end
foo(1, 2, 3)
