> As the article states, this is a social/community issue, if every application has it's own language and syntax that is a huge barrier for others coming to work on it. Every application already has its own vocabulary, which is a huge barrier for others coming to work on it (seriously: try to check out the Linux kernel, or Firefox, or the Python interpreter, and try to start hacking on them). Macros and custom syntax can help make that vocabulary more understandable, in the same way that functions can help make control flow more understandable.
