[julia-users] Self-referential type array

[Luke Stagner]

Hello all,

I know it is possible to have a self-referential type like the following

type SelfRef
   obj::SelfRef
   SelfRef() = (x=new(); x.obj=x)
end

what I want to do is have obj be an array of type SelfRef so I can make a 
tree-like structure. I tried the following

type SelfRef
   obj::Array{SelfRef,0}
   SelfRef() = (x=new(); x.obj=Array(x,0))
end

but that throws the following error (on nightly)
julia> a=SelfRef()
ERROR: no method Array{T,N}(SelfRef)
 in SelfRef at none:3

Is there anyway I can make this work?
