* A contract for a cache backends which store variables in volatile
* memory and as such support receiving any variable type to store.
*
* Note: respect for this contract is up to each individual frontend.
* The contract can be respected for a small performance boost, but
* the result is marginal except for cases with huge serialized
* data sets.
*
* Respected by the VariableFrontend which checks if the backend
* has this interface, in which case it allows the backend to store
* the value directly without serializing it to a string, and does
* not attempt to unserialize the string on every get() request.
