It's a hash slice, which contrary to the sound, is not a really
bad-flavored soft drink. It selects all elements in %server with keys
defined by the list from evaluating @temp in a list context. The
values being assigned come from the right of the equals, but there are
none, so all it does is *create* those elements and provide them with
*undef* values. Nearly always, this means that the hash is being used
as a "set" type rather than a key-value data structure, and that
exists() will be used later to see if an element has a key, regardless
of the value.
