julia导入包存储为变量

有没有一种方法可以通过编程方式导入模块,比如?

deps = [ "HypothesisTests", "Plots", "MLDataUtils", "ArgParse",
        "GraphViz", "Cairo", "CSV", "JLD", "FreqTables",
        "MLBase", "Compat"]

for dep in deps
    Pkg.add(dep)
    try
        import dep   # <-- how?
    catch
        try
           Pkg.build(dep)
        catch
           nothing
        end
    end
end

Pkg.update()
