I've done something similar for URLs (stops you mixing up whole URLs, substrings of URLs and regular strings), relative vs absolute time (easy to mix these up when there's several of these around and you're subtracting/adding to create new times) and color spaces (stops you mixing up tuples of RGB and HSL values). Feels very worthwhile for object IDs as well as there's always other variables around you could get them mixed up with.
