| <p> |
| Up until now, the most basic ingredient is missing: creation of and access |
| to local variables in the stack. When recursion comes into play, you will |
| soon realize the need to have true local variables. It may seem that we do |
| not need this at all since an unnamed lambda function cannot call itself |
| anyway; at least not directly. With some sort of arrangement, situations |
| will arise where a lambda function becomes recursive. A typical situation |
| occurs when we store a lambda function in a <a href="http://www.boost.org/libs/function" target="_top">Boost.Function</a>, |
| essentially naming the unnamed lambda. |
| </p> |
| <p> |
| There will also be situations where a lambda function gets passed as an argument |
| to another function. This is a more common situation. In this case, the lambda |
| function assumes a new scope; new arguments and possibly new local variables. |
| </p> |
| <p> |
| This section deals with local variables and nested lambda scopes. |
