Design vows

The game is developing in D programming language, thus we'd like to expose all power of compiled languages with powerful meta programming facilities.While designing game structure developers have to take following notes in the account:

• The game is open-source and we have no need in extra run-time configuration flexibility. Modules are source bundles that are compiled into the engine.
• Maximum usage of compile-time optimizations, all things that could be done while compilation - have to be done in compile-time. This rule can be relaxed for some cases, but the main idea is creating modular system using meta programming.
• No boilerplate! Use compile-time DSL's to avoid repeating code.
• Multiplayer based. Single-player mode is a multiplayer mode with one player. This paradigm saves many efforts for maintaining classical single-player code with multiplayer one.
• Performance oriented. Anybody hates laggs, therefore concurrency, compile-time optimizations and accurate memory allocation should be used.

Recomendations

• Avoid singletons, they break concurrent design.
• Use compile-time interfaces, strategy pattern.
