The Phoenix library enables functional programming (FP) techniques such as higher order functions,
|
|
/lambda/ (unnamed functions), /currying/ (partial function application) and lazy
|
|
evaluation in C++. The focus is more on usefulness and practicality than purity,
|
|
elegance and strict adherence to FP principles.
|
|
|
|
FP is a programming discipline that is not at all tied to a specific language.
|
|
FP as a programming discipline can, in fact, be applied to many programming
|
|
languages. In the realm of C++ for instance, we are seeing more FP techniques
|
|
being applied. C++ is sufficiently rich to support at least some of the most
|
|
important facets of FP. C++ is a multiparadigm programming language. It is not
|
|
only procedural. It is not only object oriented. Beneath the core of the
|
|
standard C++ library, a closer look into STL gives us a glimpse of FP already in
|
|
place. It is obvious that the authors of STL know and practice FP. In the near
|
|
future, we shall surely see more FP trickle down into the mainstream.
|
|
|
|
The truth is, most of the FP techniques can coexist quite well with the standard
|
|
object oriented and imperative programming paradigms. When we are using STL
|
|
algorithms and functors (function objects) for example, we are already doing FP.
|
|
Phoenix is an evolutionary next step.
