It definitely cost us time simply trying to understand the class layout
visually (ie, when IDE support is barely available).
You don't need to see the function bodies in the class definition, you want
to quickly see what a class has and does.

Uggh! I absolutely do not agree with this. You should rely on documentation or an IDE class overview for these things *not* alter the language. In lieu of IDE support just use ddoc comments for methods and properties and compile the documentation for each build.
