PHP
If you have a function that takes an optional parameter – e.g.
function blah($xx,$yy='Default',$zz){ ....
You can use the function and ensure that the optional parm always takes the correct default (even if the definition changes) by passing a NULL to it. e.g.
...
$mydate=blah($something,NULL,$more);
...
