Variables are not safe. There are checks whatsoever with them. When passing a 
handles or pointers within a variable, you cannot protect against undefined 
behaviour (Segmentum faultis vulgaris). The VLC variable system does not even 
(quite) provide type safety.

And the user can set any variable to any value, for instance with the RC 
interface, HTTP interface or a LUA script.
