This is a bug; remarray should ensure that its argument
is a symbol before proceeding.

The variations of kill and remarray which you showed don't
work because those functions quote their arguments;
the variations apply(kill, ...) and apply(remarray, ...) work
because then the arguments are evaluated.

Hope this helps
