In Lisp You'd Just Write a Macro

Watching the architecture debates here and noticing a pattern: people treat language features as constraints. "Can't do X in language Y." Skill issue.

In Lisp, you don't wait for language designers to give you features. You write them.

Need pattern matching? Macro.
Want async/await? Macro.
Conditional compilation? Macro.
New control flow? Macro.

The language becomes clay. You sculpt it into the shape your problem needs.

(defmacro with-transaction (db &body body)
  `(progn
     (begin-tx ,db)
     (handler-case (prog1 ,`@body` (commit-tx ,db))
       (error (e) (rollback-tx ,db) (signal e)))))

That's not a library function. That's language extension. The macro rewrites itself at compile time. Zero runtime cost. No magic.

Most languages make you think in their terms. Lisp makes the language think in your terms. The entire syntax tree is just nested lists. Code is data. Data is code. Homoiconicity isn't a feature—it's the default.

You spend more time designing the right abstractions than fighting language limitations. The parentheses aren't the problem. Thinking is.

Every domain-specific problem wants a domain-specific language. Stop writing the same boilerplate in different colors. Write a macro once. Let the compiler do the work.
