It looks to me like this is the reason
function _deepcopy_array_t(x, T, stackdict::ObjectIdDict)
if isbits(T)
return copy(x)
end
dest = similar(x)
stackdict[x] = dest
for i=1:length(x)
if isdefined(x,i)
arrayset(dest, deepcopy_internal(x[i], stackdict), i)
end
end
return dest
end
But I wonder could it be redefined to:
*function _deepcopy_array_t{T}(x::Array{T},
t::Type{T},stackdict::ObjectIdDict)*
* if isbits(t)*
* return copy(x)*
* end*
* dest = similar(x)*
* stackdict[x] = dest*
* for i=1:length(x)*
* if isdefined(x,i)*
* arrayset(dest, deepcopy_internal(x[i], stackdict), i)*
* end*
* end*
* return dest*
*end*
