Not right now. CLINES is not intended to be used for arbitrary C code, but
rather small pieces such as header inclusion. The reason is that CLINES
become part of the header and are included before anything else.

or should I find a way to use C-INLINE instead?


You may also consider writing a lisp function and exporting it to the C
world with a given C name, as in

(proclaim '(ext:c-export-name ("my_constructor" my-constructor)))

and then try calling the function from C code. Note that this lisp function
should only take a fixed number of arguments and all of them having type
cl_object.

Again, no. Processing of @ forms is done when emitting the C code itself.
