Reassemble spliced tuple fails

[maleadt]

The following fragment fails to run:

function main()
    foo = 1
    bar = [2, 3]
    foobar = (foo, bar)

    broken = (foobar...)
end
main()

I get:

ERROR: type: apply_type: in Vararg, expected Type{T<:Top}, got (Int64,Array{Int64,1})
 in main at /tmp/bug.jl:6
 in include at boot.jl:244
 in include_from_node1 at loading.jl:128
while loading /tmp/bug.jl, in expression starting on line 8

While, if bar is set to a simple literal, or even to a tuple (e,g, bar = (2, 3) instead of bar = [2, 3]), everything works normally.
