The problem is not macros, it is concatenation of identifiers. I stumbled upon this a lot when working with CSS preprocessors which allow you to write code like this: .user { &--profile { color: red; } } Now, searching for "user--profile" CSS class becomes imposible. Despite this, SASS and similar preprocessor seem to be popular and used almost everywhere. Well, I never had high expectations of front-end developers, so I am not very disappointed. So I think as long as you don't break identifiers, the code should be searchable. But, your IDE will probably not able to help you with auto-complete and navigation.
