 When using {{{get_query_var($var)}}} or {{{$GLOBALS['wp']->get($var)}}}
 and {{{$var}}} is the name of an unexistant query variable, those
 functions will return an empty string.

 Next to that there is no function that provides information about whether
 or not a specific query variable has been set.

 I therefore suggest to make both functions able to optionally return a
 chooseable default fallback value then the empty string we have.
