Is there a scripting language for C++ (like perl) which can be used for rapid development and use some tool which can convert into C/C++ program to get higher performance f
For Python, I sometimes find psyco useful. Not sure if there is any equivalent for perl though.
When choosing a language for a task, I find it more useful to choose the language most suited for the job. If the job asks for more performance than a scripting language can provide under normal conditions, it is usually better to just switch than to bend over backwards to try to make your code fast.
