If they make the documentation hard to read and understand, they're<br>

I can only say that I have found the occasional example in the Unix<br>
manual pages to be a lifesaver, and that the presence of examples in<br>
the R documentation has often made it straightforward to use something<br>
whose description was not particularly helpful. I suppose I can also<br>
say that "show me a list of places where this method is called" has<br>
been extremely informative when working on Smalltalk, even though those<br>
aren't *crafted* examples.<br>
<br>
Examples *instead* of documentation would be a bad thing.<br>
Examples *mixed in with* documentation can be distracting.<br>
<br>
So you have a library module.<br>
There are<br>
- source code<br>
- documentation<br>
- examples<br>
Thanks to the magic of hypertext, these things don't have to be in the<br>
same view. One reason for separating them is that somethings an<br>
example *has* to be an example of several things, so it's nice that it<br>
can be pointed to from several places, rather than duplicated.<div class="HOEnZb"><div class="h5"><br>
