Comment:

 In PHP there is no such thing as "return by reference" by the normal
 definition.  PHP always uses references for return variables.  The only
 exception is when there's a scope conflict, as in, {{{return
 $GLOBALS['abc'];}}} or {{{return $this->var;}}} when PHP implicitly
 returns by value.

 Most of the examples cited above are probably returning cached objects,
 which would be maintained as separate copies unless explicitly referenced
 when returned.

 plugins_api() returns a local variable and needs no special treatment.

 Enjoy!
