The manual is quite complete, and a lot of people find that a problem, because it can be hard to tell what is important and what isn't. What is Scalar Context? Every Perl expression is in one of two contexts, either list context or scalar context, depending on whether it is expected to produce a list or a scalar. Many expressions have quite different behaviors in list context than they do in scalar context.
