There is no single solution to such problems. It's a matter of creating rules and lot of work to enforce them as years pass. If you talk about Holy things you are pushing this discussion toward a stupid direction. > It also demotivates and alienates programmers. Many programmers are able to understand the advantages of removing some unnecessary freedoms.

I was talking about fixing bugs, improving strength, maybe later adding super-packages, and generally taking a good look at the literature about the damn ML-style module systems and their theory. > So you think the subset of D that's CTFE-able is good enough to make an > interactive console that's actually useful? The built-in interpreter needs some improvements in its memory management, and eventually it may support exceptions and other some other missing things. Currently functions can't access global mutable state in the compile-time execution path, despite they don't need to be wholly pure. But in a REPL you may want to do almost everything, like mutating global variables, importing modules and opening a GUI window on the fly, etc. SO currently the D CTFE interpreter is not good enough for a console, but I think it's already better than nothing (I'd like right now a console able to run D code with the current limitations of the CTFE interpreter), it will be improved, and it may even be made more flexible to be usable both for CTFE with pure-ish functions and in a different modality for the console. This allows to have a single interpreter for two purposes. Most modern video games are partially written with a scripting language, like Lua. So a third possible purpose is to allow run! -time execution of code (so the program needs the compile at run time too), avoiding the need of a Lua/Python/MiniD interpreter. Bye, bearophile
