me not!

it is more than logical that this should work, as = is always evaluated
first!

i don't think so.

why?

whats the difference between

function( anotherFunction() );
function( $var = 'value' );

???

why should this not work?

for example in C i often see this to clarify parameters

function(true, false, true);
or
function($use_utf8 = true, $return = false, $escape = true);

what do you think is easier to read? and why should this not work in PHP?
