More docs on the sandboxed execution stuff: <a href="https://www.gnu.org/software/guile/manual/html_node/Sandboxed-Evaluation.html#Sandboxed-Evaluation" rel="nofollow">https://www.gnu.org/software/guile/manual/html_node/Sandboxe...</a><p>Includes a great quote:<p>> Sometimes you would like to evaluate code that comes from an untrusted party. The safest way to do this is to buy a new computer, evaluate the code on that computer, then throw the machine away. However if you are unwilling to take this simple approach, Guile does include a limited “sandbox” facility that can allow untrusted code to be evaluated with some confidence.
