The problem with the Loop macro isn’t the English, it’s that it doesn’t look anything like the rest of the language. It’s like finding some embedded Python in your Java; even if you’re fine with using Python, it’s going to be pretty hard to work with when you’re in Java mode. Also, macros are much harder to debug, especially when the macro expansion code itself crashes. The loop macro does a lot of work, which makes it a particularly annoying macro to fix when things go wrong.
