I understand that macros are both the mechanism to generate code at compile-time as well as for generating code at runtime. But it doesn't look like the linked project does the latter. In fact, there are mentions in the README that indicate that there is no runtime for LISP/c at all:

> The way that LISP/c works is sort of tricky. It utilizes a lot of string manipulation and interpretation. It doesn't need to be insanely fast, though, because it's just dealing with code; the compiled result will not suffer from any slowness.

In other words, it seems that this project just allows you to generate C code from a LISP-like syntax, but doesn't allow you to `eval` during the execution of the resulting C program. There is no runtime representation of code as data as with other lisps.
