I made a small (< 7 Mb) footage of me expanding a macro through Geiser it' s here http://catonano.v22018025836661967.nicesrv.de/resources/videos/expanding.flv
The macro I am expanding is defined in the Guix code and it is supposed to deliver some forms creating and manipulating srfi-9 forms (records) but the result I see is a piece of code creating and manipulating a structure It seems to me that also the vanilla srfi-9 forms have been expanded and I' m getting the lowest level possible (there are no more macros to expand in the code I am seeing) In the Guile NEWS file I read this excerpt ** `macroexpand' produces structures, not S-expressions. Given the need to maintain referential transparency, both lexically and modular, the result of expanding Scheme expressions is no longer itself an s-expression. If you want a human-readable approximation of the result of `macroexpand', call `tree-il->scheme' from `(language tree-il)'. so I' m not sure now: is il-tree->scheme being called in my example ? or am I supposed to call it myself ? Thanks in advance
