On the contrary, design patterns are everywhere, and developers often use
some form of them without even knowing. In such cases it often only
requires some small form of code tuning to get a better design.
Simple example: Ever used TAction in Delphi or Lazarus? Yes? Well, then you
have been using the Command pattern (well some form of the Command
pattern). VCL actually has quite a few design patterns implemented. And to
reiterate an earlier point I made: design patterns are *not* a code
template, they are a design guideline for solving a common problem, and
each design may differ in implementation.
