Chunked Seqs

Leveraging the structure of data when sequencing

Scenario

• Viewing all data structures as sequences is powerful 
• High-level sequence model is ideal for code understanding (vs. loops) 
• Laziness is critical, esp. not realizing full intermediate results 
• But 
  • Per-step overhead 
  • Fails to leverage efficiencies of representation

Idea 

• first/rest imply item-at-a-time steps 
  • But nothing about map et al does 
• Introduce coarser-granularity seqs 
  • could leverage block-like indexed addressability of representations 
• Backwards compatible with item-at-a-time seqs 
• Should be faster - amortize overhead
