I have never investigated this, but I feel that PL pragamtics and PL-feel is relatively under researched. I talked about this with colleagues a few years back, but we had very distinctly different feelings about what we were doing when writing C vs C#: C often feels more like writing text that will be translated to code while C# already feels like you are manipulating code. It makes no sense when I write this out but that's phemenology for ya.
