Concept exercises

[rikedyp]

This issue is to gather suggestions for concept exercises to form a basic syllabus. The list here will be updated to form the canonical list, but individual concept exercises will have their own issues to track progress.

• arithmetic
• primitive reduction over vectors
• primitive reduction over general arrays (requires: shape, reshape)
• reduction with user-defined functions
• dfns (monadic / dyadic / ambivalent / guards)
• errors (error guards, :Trap, ⎕TRAP maybe)
• compress (filter using replicate with Boolean mask)
• selection
  • square bracket index (requires or introduces matrices?)
  • squad
  • pick
• each (AKA map)
• stranding of numbers (e.g. 2 2+2 2+2)
• parsing simple expressions (long right scope, short left scope)
• use of parentheses in expressions
• assignment (single name and pass-through e..g (var←3 and var×6+var←12)
• reshape
• stencil (requires: operators?)

Reductions would be a big one in my opinion, both vector and array.

Filters/Boolean Masks.

Map/Each.

How about Stencil? I enjoyed solving https://exercism.org/exercises/minesweeper with it https://chat.stackexchange.com/transcript/52405?m=65665691#65665691
