There was a time that I was pretty invested in the latest language features. In the late 90s during my Delphi era I used to speak at conferences on new language features, would start every conversation with the compiler dev team with "When will you implement Design by Contract" , and would actively seek out new features of every new compiler release and find ways to use every new feature. It didn't take much rationalization to justify using the latest language feature in whatever code I was building, and I must admit I wrote some pretty arcane code in my time.
These days I no longer live on the language leading edge, I program in C# or VB.NET or Delphi Prism to get the task done and I'll let you in on a secret ... with the exception I guess of LINQ I don't really use many new Language features. Sure, I understand what anonymous methods and lambda expressions are, but to me they seem to be simply building blocks needed to get to LINQ rather than essential features the the Language that demanded inclusion for their own sake. So I have not invested too much time learning everything there is to know about these new language constructs. In the immortal words of Roger Murtagh: "I'm too old for this ... errr ... stuff"
Sometimes it seems to me that it is possible that being able to convert an expression to a delegate or compress it to a lambda expression results in cleaner looking code. And this is where Refactor Pro comes in, Refactor is able to parse my code and tell me when an expression can be converted to use a new Language feature. I don't have to know much if anything about the feature, I just trust that Refactor will create correct code - and if the result looks cleaner I go for it, and if not I can simply Ctrl-Z undo.
Since one of the key developers of this feature was Dustin Campbell,
F#
expert, C# MVP and VB PM for Microsoft I am fairly confident that the
resulting code will be superb. It's as if I am pair programming with
someone who I can trust to learn all this arcana for me and suggest how
to improve my code, and I can focus on the problem domain.
It's like in my universe ... Clippy has been retasked to Visual Studio except he's been replaced by a little Dustin and he has to check all of my code before it gets checked in.
