The complexity (and the slowness) of a C++ compiler now is mostly due to the complexity - and the slowness - of the built-in interpreter of the template meta-language. There are other, saner languages, such as Common Lisp, where the meta-language is indistinguishable from the language itself, which, in addition to its greater simplicity, greatly contributes to the reasonable compile times. In the C&amp;#x2F;C++ land, it might have been possible to use a similar approach instead of introducing a separate macro&amp;#x2F;template syntax, a good example being the approach taken in the design of ASP (active server pages), PHP, and the like.</text><parent_chain><item><author>koja86</author><text>You might find this project kind of interesting:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;isocpp&amp;#x2F;CppCoreGuidelines&amp;#x2F;blob&amp;#x2F;master&amp;#x2F;CppCoreGuidelines.md&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;isocpp&amp;#x2F;CppCoreGuidelines&amp;#x2F;blob&amp;#x2F;master&amp;#x2F;CppC...&lt;/a&gt;&lt;p&gt;As a day-to-day C++ practitioner I like it.&lt;p&gt;...Yet I am not fully convinced that the general idea of language evolution implemented as ruleset outside of the language itself is the way to go.
