> This epic aims to introduce code generation capabilities for automatic operator fusion, which helps to reduce the number of materialized intermediates, reduce the number of input scans, exploit sparsity, and reduce compute, while significantly reducing the development effort compared to hand-coded fused operators. 
> For the 1.0 release, we will introduce code generation as an experimental feature, covering an extended version of SPOOF's code generator as described in the following paper:
