/*
* Compile the stupid 'declare' language construct.
*
* According to the PHP language reference manual.
* The declare construct is used to set execution directives for a block of code.
* The syntax of declare is similar to the syntax of other flow control constructs:
* declare (directive)
* statement
* The directive section allows the behavior of the declare block to be set.
* Currently only two directives are recognized: the ticks directive and the encoding directive.
* The statement part of the declare block will be executed - how it is executed and what side
* effects occur during execution may depend on the directive set in the directive block.
* The declare construct can also be used in the global scope, affecting all code following
* it (however if the file with declare was included then it does not affect the parent file).
* <?php
* // these are the same:
* // you can use this:
* declare(ticks=1) {
* // entire script here
* }
* // or you can use this:
* declare(ticks=1);
* // entire script here
* ?>
*
* Well,actually this language construct is a NO-OP in the current release of the PH7 engine.
