Questions we should work on answering:

• Q: What are we trying to accomplish in this space? What are the intended use cases?
  • Graphics.
  • Simulation.
  • Scientific Computing.
• Q: What are the design requirements and principles?
  • Builds on top of the mdspan feature and interoperates with the 2D Graphics proposal.
  • Clear path for implementing operations with a high performance BLAS library.
  • Supports both compile-time and run-time meta-data (extents, striding, padding, etc).
  • Supports mixing compile-time and run-time meta-data (a la mdspan).
  • Separate data storage from algorithms (e.g. the string_view model).
  • Supports mixed precision operations.
  • Supports non-fundamental numeric types (e.g. fixed-point, units, chrono::duration etc.)
• Q: What capabilities must be included in a minimum viable product (e.g. version 1)?
  • Abstractions for element iteration (e.g. multi-dimensional for loop).
• Q: What are the risks?
  • Is prohibitively difficult to learn for users with basic knowledge of linear algebra
  • Introduces run-time overhead over using graphics oriented geometry libraries (e.g. GLM)
