This function marks one or more variables as temporary, that is, the values of these variables will not be saved when the World is closed. This is the standard behaviour for variables, so this function is only needed to undo the efects of the $world->makepermanent function.

The names of the variables are passed as a string, including the $, @ or % prefix. Be careful to use single quotes (or \ inside double quotes) to avoid variable interpolation.
