Nearly every module entry in the documentation has a headline with the pattern <module name -- description>, followed (in the second line) by <Source code: directory>. In the entry concerning pdb (https://docs.python.org/3/library/pdb.html), there is no hint where the source code is located. This is especially annoying, because the user of the Python Debugger is explicitely invented to extend the module´s capabilities ("The debugger is extensible – it is actually defined as the class Pdb. This is currently undocumented but easily understood by reading the source."). A link to the source code should be added as the second line. The same thing should done for symtable, compileall and perhaps some other modules, which I haven´t checked by now.

Excuse me, but it would be nice to fix the documentation of the modules symtable and compileall too. Thanks.
