[julia-users] Help with convoluted types and Vararg

[Seth]

Hi all,

I have the following on 0.4.6-pre+18:

z = [Pair((+,1,5,7), 3), Pair((-,6,5,3,5,8), 1)]
type Foo
    x::Array{Pair{Tuple{Function, Vararg{Int}}, Int}}
end


and I'm getting

julia> Foo(z)
ERROR: MethodError: `convert` has no method matching 
convert(::Type{Pair{Tuple{Function,Vararg{Int64}},Int64}}, 
::Pair{Tuple{Function,Int64,Int64,Int64},Int64})
This may have arisen from a call to the constructor 
Pair{Tuple{Function,Vararg{Int64}},Int64}(...),
since type constructors fall back to convert methods.
Closest candidates are:
  Pair{A,B}(::Any, ::Any)
  call{T}(::Type{T}, ::Any)
  convert{T}(::Type{T}, ::T)
 in copy! at abstractarray.jl:310
 in call at none:2


It's probably a stupid oversight, but I'm stuck. Can someone point me to 
the error?
