This required some changes to how we name variables in DSL. When-expressions are designed to expect a local C++ variable with the same name as the layout key. This constraint means our DSLVar variables CANNOT have the same name as the layout key. Now, all DSL variables are given a prefix. We try to keep the code tidy by using just a leading underscore as the prefix, where it's safe to do so. (The C++ naming rules put some underscore-names out of bounds, but underscore followed by a lowercase letter is safe.)
