> it's possible to add additional abbreviations to s-expressions It is, and infix notations have been added many times, going back at least to Vaughan Pratt's CGOL in the 1970s. Yet none of these notations have ever caught on very much among Lisp programmers. I understand that the syntax is a barrier to newcomers, but there's no point in arguing that it should be changed, because one really does get used to it, and even to like it. You might as well tell the Mexicans (or Indians, or Thai, or Chinese, etc.) not to make their food so spicy. Yes, it takes some getting used to, but to change it would be to ruin it.
