Early Draft
This SRFI displays the Scheme code that results from expanding a macro, without actually evaluating that code -- an essential tool for debugging macros.
Common Lisp has standard macroexpand and macroexpand-1 functions.
https://doc.scheme.org/surveys/MacroExpand/
(macroexpanded? form) => boolean
(macroexpand form [environment]) => expansion, expanded?
(macroexpand-1 form [environment]) => expansion, expanded?
(macroexpand-n form [environment [n]]) => expansion, expanded?
(macroexpand '(cond (a 1) (else 2)))
The implementation of this SRFI depends deeply on the macro systems available in each Scheme implementation, and how those macro systems are implemented in detail.
