From: Daniel Berger Date: 2007-10-08T01:19:57+09:00 Subject: Quick Enumerable#sort_by internals question Hi, In enum.c there's this bit of code in the sort_by_i function. if(RBASIC(ary)->klass) { rb_raise(rb_eRuntimeError, "sort_by reentered"); } Can you show me a test case where this error can happen? Just curious. Thanks, Dan
