Nothing happens when run from the command line or when included

[origamist]

Steps to reproduce:

Copy the code from the example into a file, e.g. plot.jl:

using Gaston, SpecialFunctions

set(term = "qt")

x = y = 0:0.075:10
surf(x, y, (x,y) -> besselj0(y)*x^2, with = "pm3d",
     Axes(view = (45, 45),
          pm3d = "lighting primary 0.5 specular 0.4",
          key = :off)

In a REPL, run it using include("plot.jl"), or run it from the command line using julia plot.jl

Expected:

Something shows up, like when the code is copy-pasted into a REPL.

Actual:

Nothing shows up.

Works for me.

What happens if you execute the code in the REPL instead of includeing it?
