Anonymous Callbacks != Callbacks

Callbacks have been around forever in C using named functions, and are not specific to either the current generation of programming languages or programmers. One can still use a named function instead of a locally constructed lambda to represent a callback in a high level languages.

The primary difference is that when declaring named functions non-locally, one must explicitly share state through the parameter rather than implicitly sharing state through lexical scoping. It seems more accurate to label the problem of nesting lambdas to the point of ambiguity as "Lambda Abuse" or "Lexical Scoping Abuse" rather than "Callback Hell".
