@maybe macro

[gdkrmr]

I have a project with longer calculations and have created a macro to automatically save/calculate/reload object. I am using JLD2 for it and there is something similar in YAXArrays.jl.

Do you think it would be possible to create a more general version that can be integrated into FileIO.jl? And: would it make sense to integrate something like this into FileIO.jl?

Syntax is as follows:

@maybe x => "x.jld2" begin
  x = 1
end

If x.jld2 exists, it is loaded and the begin ... end part is skipped, if x.jld2 doesn't exist the expression is run and x is saved in x.jld2.
