With 3.6 not bound by compatibility with external imports, dead code can go.  It is an annoying distraction.  The resource saved is space in package and module content listings and maintainer time and attention.  

1. module  It is obsolete at least since 2.6 and deprecated in 2.7.11 and 3.4.4+ in #24199.  If  IDLE is ever separately versioned again, idlever should be an attribute in idlelib.__init__.

2. file help.txt and its dedicated viewer editor.HelpDialog.  help.txt is out-of-date and not maintained, as it was replaced years ago by Docs/library/idle.rst.  Since Fall 2015, IDLE uses to display help.html with formatting and index. See #16893.

3. stackviewer.StackBrowser.keys.  I removed this trivial and no-longer used method in #24790, and then restored it in the face of an objection and the lack of overt criteria for such removals.  I expect the class to get far more drastic changes than this.

Note: 'unused' is determined by grepping the name in consideration in .../idlelib/*.py, where ... == <repository path>/Lib.  IDLE => Edit => Find in Files, Alt-F3.

Issue #27156: Remove obsolete code not used by IDLE.

Patch removed 1 & 2.

4. macosx.runningAsOSXApp and macosx.isCarbonAquaTk were deprecated in then current versions on 2014 Feb 27 by New Deily in #17654.  In particular, 67a7a49e7b78 was applied to the future 3.4.1.  Ned, do you have any objection to removing these now, for 3.6?

I checked the usage of isXyz functions outside the definitions and deprecated functions.  isAquaTk: 8, isCarbonTk: 2, isCocoaTk: 5, isXQuartz: 0.  I gather from that Carbon might still be in use on machines with early 8.5 and that XQuartz is still in use and might be needed in the future.  Also, since exactly 1 of 'Aqua' and 'XQuartz' are true on current machines running 8.5+, they are currently reduncant, but this could change in the future. So I don't propose any deletion for this group.

No, go right ahead.  Nobody should be using them.  And I concur with keeping the others around for the time being.

3 and 4 removed. Closing at least until I find something else that is not part of a refactoring but needs at least a question answered.
