While this probably isn't a practical way to do any real work, running it with --compile=min gives some idea what might be possible soon:

    $ julia --compile=min -e '@time (using GR; plot(rand(20)))'
      0.375836 seconds (368.83 k allocations: 20.190 MiB, 1.65% gc time)
    $ julia --compile=min -e '@time (using Plots; plot(rand(20)))'
      4.302867 seconds (6.41 M allocations: 371.485 MiB, 5.07% gc time)
