parseInt( :number => 'afy', :radix => 30, :foo => false );

associative array

parseInt( {'number' => 'afy', 'radix' => 30, 'foo' => false } );

PHP

parseInt( array( 'number' => 'afy', 'radix' => 36, 'foo' => false ));

associative array

Java

parseInt( new HashMap() {­{ put( "number", "afy" ); put( "radix", 36 ); put( "foo", false ); }} );

map (associative array)
