Hmmm, maybe I did not made myself perfectly clean. I do use mod_perl just now, but it has several drawbacks. One such drawback is described in Fast shared data structures.

In short, the problem is with large, mostly-read data that contains embeded perl code. For example, ePerl templates. For efficiecy reasons they must be pre-compiled. That's perfectly easy so far. But I want to change the templates while server is running. No chance to do this efficiently in Apache one-process-per-request architecture.

So I come up with an idea to store templates in GDBM. But what about embeded perl here? If I whould store it in source form, it will be terribly slooow, compile it in every HTTP request. If I compile it in every httpd process, it will be terribly large. Now, I must pre-compile perl code and store it in GDBM in pre-compiled form.

How to do that?

Ad B::Bytecode. I have checked this module, and it looks good. But I can't fugure out how to use it no a piece of perl source that I have in scalar variable instead of whole perl program. Could anyone please help me with this. Some simple 3-line example would be more that sufficient. Thanks a lot.
