/** | |
* Base contract that all upgradeable contracts should use. | |
* | |
* Contracts implementing this interface are all called using delegatecall from | |
* a dispatcher. As a result, the _sizes and _dest variables are shared with the | |
* dispatcher contract, which allows the called contract to update these at will. | |
* | |
* _sizes is a map of function signatures to return value sizes. Due to EVM | |
* limitations, these need to be populated by the target contract, so the | |
* dispatcher knows how many bytes of data to return from called functions. |
