>...I've often seen it used to add complexity where none is necessary.

This reminded me of a great blurb about Niklaus Wirth's approach to languages:

>Wirth’s philosophy of programming languages is that a complex language is not required to solve a complex problem. On the contrary, he believes that l languages containing complex features whose purposes are to solve complex problems actually hinder the problem solving effort. The idea is that it is difficult enough for a programmer to solve a complex problem without having to also cope with the complexity of the language. Having a simple programming language as a tool reduces the total complexity of the problem to be solved. [0]
