Deprecation of `require` and parallel code execution.

Hi, 

In Julia 0.3.5, the following loaded the data and code/functions on all workers:

addprocs(3)
require("data_loading_script.jl")
require("functions.jl")

Now, Julia 0.4.5 warns about deprecation of require and suggests switching to 'using' or 'import'.

What is the equivalent in Julia 0.4.5 for the above three lines that worked fine in Julia 0.3.x?

Hi.

Use include("file.jl")  and add @everywhere in front of the definition of every function to be used inside the @parallel loop.

Would it also work for pmap()? I don't have any @parallel loops.

Hi.

Yes, exactly the same with pmap()

Silly example:

addprocs(3)

@everywhere Test(i)
     println(myid())
end

i=1:1000;
pmap(Test,i)

if you do not use @everywhere, it will not work.
