Back in the naive olden days, Microsoft released ActiveX, where a web page could 
load executable objects (!) from the internet and run them in the browser.

It quickly became apparent that this was a disaster, as lots of people on the

CTFE on D doesn't allow making any system calls. This is on purpose.
