Code improvement:The order of evaluation of subexpressions has an impact on both register allocation and instruction scheduling. In the expressiona * b + f(c), it is probably desirable to callfbefore evaluatinga * b, because the product, if calculated first, would need to be saved during th...

When using the JavaScript engine, expressions are pre-processed before evaluation in order to make some of the Legacy ExtendScript expression syntax readable by the new engine. However, these pre-processing tasks are not performed when evaluating expressions from a .jsx expression function library or...
Its virtual machine, called Parrot, is unusual in providing a large register set, rather than a stack, for expression evaluation. Like Perl itself—but unlike the JVM and CLR—Parrot allows variables to be treated as different types in different contexts. Work is underway to target other ...
