With a plugin-system it would be easy to handle this declaratively.
We need a way to extend the supported key-value pairs. This would be done in check_tanh plugin package.
Then you need to build-depend on the new check_tanh package.
I guess that most developers feel that this is very complicated. I feel the same, but I **think** it is not.
The structure is straight forward. It just feels complicated. The check_tanh package
can be create in just a few minutes.
