Care and attention to detail was given, painstakingly, to the design and implementation of Phoenix. The overall design of the framework is well structured and clean. In this chapter, we shall see the main concepts behind the framework and gain introductory insights regarding its design.


Implementation wise, not a single macro was used. Macros cause more trouble than its worth, regardless if they are used only in the implementation. A very early version of the framework did use macros to generate redundant code. The experience was to say the least, painful. 1) The code is so much more difficult to read 2) Compile errors take you in the middle of nowhere in a meaningless macro invocation without the slightest clue whatsoever what went wrong. The bottom line is: Macros are plain ugly. Exclamation point! No to macros. Period.
