I started using Python in 1997 and found it profoundly mind-expanding since my previous experience with languages was limited to C/C++ and Pascal. But over the years I learned other languages and came to see missed opportunities and outright mistakes in the original design that I don't think a more experienced student of programming language design would have made. Many of the original mistakes have now been corrected but the churn in the language this has required means that it no longer "fits in my head" the way Ruby or C do.
