A few ideas:

1. If it's immediately recursive (that is, contains a pointer to 
itself), just use the type itself somehow. You may not be able to 
do this with recursive templates.
2. If the data itself is static, and not actually containing 
different things, defer the construction of the Meta members 
until needed. In other words, make them structs with a member 
which accesses the meta when requested.
3. In a project I have which constructs a parallel type on 
existing types, I use `opDispatch` to defer instantiation of the 
members until later. This may or may not work for you depending 
on the use case (you can't introspect `opDispatch`).
