[drcode]

Can you find the quote? I'd be surprised to learn that.

For my own code, it consists of maybe 10% macros. I would say the same is true for PG's code (for the hacker news app- The arc core libraries have more macros but are a special case.)

Unless, of course, if you mean _calling_ macros- I would agree that Lisp code often has 50% of its calls be macro calls instead of function calls.

50% code by volume being macros sounds terrifying.

Macros are like 2nd-amendment rights. You hope you never have to use them, but when you do you'd be in a world of hurt without them.
