Re: [Gretl-devel] foreign julia: gretl_export in gretl_io.jl doesn't work with julia 1.0.2

the current gretl_io.jl combined with a freshly downloaded julia-1.0.2 provokes the following error: .... julia-1.0.2/bin/julia exited with status 256 stderr: ERROR: LoadError: `write` is not supported on non-isbits arrays Stacktrace:  [1] error(::String) at ./error.jl:33  [2] macro expansion at ./gcutils.jl:86 [inlined]  [3] write(::IOStream, ::Array{Any,2}) at ./io.jl:532  [4] gretl_export(::Array{Any,2}, ::String, ::Int64) at /home/ <...> /.gretl/gretl_io.jl:35  [5] gretl_export(::Array{Any,2}, ::String) at /home/< ...> /.gretl/gretl_io.jl:10 Compare this entry in the julia 0.7.0 changelog (https://docs.julialang.org/en/v0.7.0/NEWS/): "Calling |write| on non-isbits arrays is deprecated in favor of explicit loops or |serialize| (#6466 <https://github.com/JuliaLang/julia/issues/6466>)." So it seems to me that gretl_io.jl needs updating. Which should it be, explicit loop or serialize?
