[julia-users] Can't make something out of nothing

[Dominique Orban]

In 0.3, I used to be able to make something out of nothing:

julia> VERSION
v"0.3.6"

julia> type Something
       s :: Nothing
       end

julia> Something(Nothing())
Something(nothing)

but no longer in 0.4:

julia> VERSION
v"0.4.0-dev+4294"

julia> type Something
       s :: Nothing
       end

julia> Something(Nothing())
ERROR: MethodError: `convert` has no method matching convert(::Type{Void})
This may have arisen from a call to the constructor Void(...),
since type constructors fall back to convert methods.
Closest candidates are:
  convert{T}(::Type{T}, ::T)
 in call at base.jl:38


How do I achieve the same effect?

Thanks.
