True enough. But the modern crop of first-tier VCSen – Bazaar, Git,
Mercurial – are the ones to choose from. Anoyone recommending a VCS tool
that has poor merging support (such as Subversion or, heaven help us,
CVS) is doing the newcomer a disservice.

Learn the basics in all three of those, and learn one of them well. My
choice is Bazaar, because it has a very friendly command-line interface
and has excellent support for repositories created by all the others :-)

Note that following that specific convention will match the default in
many programmers's text editors for highlighting those entries to bring
them to the programmer's attention. The defaults for PyLint also report
such comments in the code.

The two practices above – use a modern VCS, maintain TODO items such
that the computer can report them automatically – are so useful and so
inexpensive that I think anyone aspiring to become a good programmer is
foolish if they omit them on any project.
