Share an already defined variable to all processes

If I have a variable already defined in one process, how can I share it with all the other processes? @everywhere foo=1 does this for a new definition of foo. But suppose I already assigned foo to a value in the current process. Now I would like to use this same variable name to access this value in all processes. What’s the correct way to do it?

I think I figured it out. In Julia 0.6.4:

@eval @everywhere foo=$foo;

In Julia 1.0 I think it’s the same except that the @eval is not required.

See that’s built to solve that exact problem.

It doesn’t seem to support Julia 1.0 yet.
