Lisp has long been touted as a good language for developing a DSL, one
reason being it's macro system. However, it has also long been realized
that DSLs implemented with macros can be extremely difficult to debug
because by the time bugs manifest the (macro) source is long gone and
its connection to the expansion text is difficult to determine.
