The VM can also run compiled scripts so you can compare a AS1/2 version of a benchmark with its haXe equivalent by running the two computations on the same computer and measuring time spent. You're welcome to run your own benchs if you don't believe it :) > But, of course, sounds great compared to PHP. Have you tested PHP with > the Zend Accelerator or any of the free accelerators? Yes we use both Zend Accelerator and EAccelerator for our old PHP devs. Still, such technologies mainly cache the bytecode, they don't improve so much interpreter computation speed. >> A language is not just syntax, it's also architecture and a type system. >> For example you will be able to do some kind of remoting by sending >> Classes (not just anonymous objects) between the client and the server. > > > And this precisely is the issue, because you're trying to provide common > architecture and type system over 4 different VM-s (JS, F8.5, F Classic, > your server mod).

There will always be some, but it's ok as long as they don't hurt too much development. For example null.foo() will make a runtime exception on all platforms but not on Flash 6/7/8. At least until there is a "debug" flag that would add additional checks. > Also we've seen how "layering" of new paradigms over old engines works > with AS2, where all the compiler checks were superficial and easily > worked around at author or runtime. Yes, but I think this is an advantage, not a problem. If you have a lot of runtime checks, you endup with Java which is quite strict but not flexible. My thinking is that having a staticly typed language over a dynamicly typed runtime permit the best of both worlds, especialy if you provide enough Runtime Type Informations and Reflection.
