I had the same feeling when I first started using a lisp (which was Scheme to work through SICP and the Ableman&Sussman MIT course). I was utterly entranced by the simplicity and uniformity. It was absolutely a factor in the way syntax works in my personal language (which I use for almost everything in my day to day). I really do agree that learning a lisp can truly expand the way in which a dev views and thinks about code.

Brown university PLT labs also vouched for this approache. Their textbook starts with a descriptions of sexps as syntax saying that's the only parsing theory covered here.
