+--- seplist(list[, separator_proc[, iter_method]]) {|elt| ... }
+    adds a separated list.
+    The list is separated by comma with breakable space, by default.
+
+    seplist iterates the ((|list|)) using ((|iter_method|)).
+    It yields each object to the block given for seplist.
+    The procedure ((|separator_proc|)) is called between each yields.
+
+    If the iteration is zero times, ((|separator_proc|)) is not called at all.
+
+    If ((|separator_proc|)) is nil or not given,
+    (({lambda { comma_breakable }})) is used.
+    If ((|iter_method|)) is not given, (({:each})) is used.
+
+    For example, following 3 code fragments has similar effect.
