This is what I disagree with. If they were correct when symbols were strongly interned, the behavior shouldn't change when symbols are weakly interned. In other words, the *use* of MAKE-EQ-HASH-TABLE isn't the bug, it is the *behavior* of MAKE-EQ-HASH-TABLE that is buggy. It should retain symbols and numbers the same as it used to. BTW, the fix for this was trivial and I checked it in this morning. you need these two changes: 77c8301526fc3a8f420c2922eefad215bd8d8dba (patch) 097a3ee6c70d396a3277fb96374abbfc2da86e51 (patch) and now entries keyed by interned symbols will not drop out of EQ hash tables. Otherwise, the behavior is as before. -- ~jrm _______________________________________________ MIT-Scheme-devel mailing list MIT-Scheme-devel@gnu.org http://lists.gnu.org/mailman/listinfo/mit-scheme-devel
