Macros and metaprogramming arrive with a craftsman’s restraint. The preprocessor is not an ornate workshop of magic; it’s an exacting stencil set, meant to reduce repetitive labor and to standardize outputs across teams who must interoperate without footnotes. Compile-time checks are framed like quality inspections: they slow you down so the product will last. The compilation experience, in this aesthetic, is a measured ritual—slow builds are accepted when they mean fewer runtime surprises, and incremental feedback is preferred to frantic, all-or-nothing attempts to hide defects.
