Re: Interpretted JAVA Vs. Compiled VC++: Java Wins!
Thanks for the elaborate explenation, Jeffrey!
What would be nice to see is Euphoria being as fast as
JAVA, but keeping its fast sequences.
It would be unstoppable then.
Maybe Rob should
A. Optimise the internal code produced by the
interpretter, using age-old optimisation techniques.
B. Implement a JIT compiler instead. Euphoria only
runs on x86 based systems, so it's not that big a
deal.
Maybe one of us should write a Euphoria interpretter,
in Euphoria, that translates to Machine Code, but uses
Euphoria's built-in sequence type to store sequences.
Plus, translate all that to C using the translator,
and you have one mighty fast Euphoria implementation..
This way we Eu coders finally get a break and don't
have to grab on to JAVA or another language for speed.
Untill then, consider me a JAVA coder aswell.
I'm learning it now and find it very easy, with some
good OOP support and fine library routines.
