Why are there no Macros in this Lisp?

By far the biggest gripe conventional Lisp programmers have with the Lisp in this book is the lack of Macros. Instead of Macros a new concept of Q-Expressions is used to delay evaluation. To conventional Lisp programmers Q-Expressions are confusing because their semantics differ subtly from the quote Macro.

I use Q-Expressions instead of Macros for a couple of reasons.

First of all I believe them to be easier for beginners than Macros. When evaluation is delayed it is always explicit, shown by the syntax, and not implicit in the function name. It also means that S-Expressions can never be returned by the prompt or seen in the wild. They are always evaluated.

Secondly it is more consistent. It no longer requires the concept of Macros, but instead transforms quoted expressions to become the dominant, more powerful concept that does everything needed by either. With Q-Expressions there are only Functions and Expressions, and the language is even more homo-iconic than before.

Finally, Q-Expressions are distinctively more powerful than Macros. Using Q-Expressions it is possible to pass an argument to a function that evaluates to a Q-Expression, making input arguments capable of being dynamic. In conventional Lisps passing an expression to a Macro will always pause the evaluation, and so the arguments cannot be dynamic, only symbolic.
