+# New tests for bug 3057639 to show off the more consistent behaviour
+# of lappend in both direct-eval and bytecompiled code paths (see
+# append.test for the direct-eval variants). lappend now behaves like
+# append. 9.0/1 lappend - 9.2/3 append.

+# Note also the tests above now constrained by bug-3057639, these
+# changed behaviour with the triggering of read traces in bc mode

+
+# Going back to the tests below. The direct-eval tests are ok before
+# and after patch (no read traces run for lappend, append). The
+# compiled tests are failing for lappend (9.0/1) before the patch,
+# showing how it invokes read traces in the compiled path. The append
+# tests are good (9.2/3). After the patch the failues are gone.
