suggestion: Make

[defunkydrummer]

Suggestion: The project (as 90%) of Lisp projects, doesn't require compilation from an external command line using make.

The usual way to compile such a project (like openapi2cl) is just to load it on the REPL, either doing:

(asdf:load-system :openapi2cl)

Or, if Quicklisp is enabled and OpenAPI2CL is copied to the local project directory:

(ql:quickload :openapi2cl)

This will automatically compile and load the system in all major implementations. In general there's no need to abandon the REPL when working with Lisp projects; everything, including installing new libraries, can be done from the REPL.
