+  would greatly benefit them. Perhaps this is why they feel that

+  showing evidence gratitude when help is offered them.
+
+# Confidentiality of Bug Reports
 
 When you report a bug, you are giving up confidentiality to the source
 code and the byte code. However, I would imagine that if you have

+================================

+Python 3.7. But with this release, releases will be put on hold,as a
+better control-flow detection is worked on . Tis has been needed for a
+while, and is long overdue. It will probably also take a while to get
