Yes they do. They provide information about _intent_. Granted, some
aliases have little variance between the meanings, but when you are
reading someones code, there are two things going on. What does it do
and why does it do it? The first is closely knit to the love of the
"There is only one way to do it", since it is easier to figure out what
the code actually does. (Python?) IMHO, that is akin to treating the
human brain like a compiler.
