Ok, I just (re-)discovered that this is a non-issue: these encoding changes are done by SCM2PTR and PTR2SCM. Right now, I have a version of Guile that doesn't store scm_t_bits into the heap, and it does feel a cleaner since no scm_t_bits* <-> SCM* casts are done. Now, I'll try to completely remove the use of the scm_t_cell type (only the use, not the definition). This one is rather confusing as well since it is not used consequently (I think). _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://mail.gnu.org/mailman/listinfo/guile-devel
