I've seen too many cases where the comments explaining what a block of
code did were *wrong*, and debugging took far too long due to coders
reading, trusting, or simply being distracted by this alternate theory of
what the code was doing.

Being able to read the code itself and figure out what it's doing is a
primary programmer skill, and writing code that's not harder to figure
out than it needs to be is important too.

With regexen for eg matching logfile lines, a comment with a few
different example lines that should match can be very helpful.

Some explanation of *why* you're going to the trouble of doing something,
or a simple explanation of what task a block of code encapsulates, are
useful things for a comment block.  But line-by-line attempts at
translating code to English are counterproductive.
