I think there are too many, rather than too few, bindings in (guile). Module separation is great: it avoids name clashes (and allows one to use #:renamer or #:select), and follows the principle of least authority (granting programs only what they explicitly asked for.) > shuffle and shuffle! are two procedures that are conspicuously absent > from anywhere guile, and that I have probably reinvented every two > months or so.
