The Weekly Pearls of Raku
summary
Survey of compact Raku recipes that actually run: generating ugly numbers by building three geometric sequences, taking a cross operator product, sorting and indexing to get the 7th = 8; streaming averages via triangular sums and zip-like elementwise division exploiting the slurpy + parameter rule; sum‑of‑squares of digits using comb/map/reduce to output 15→1 and 52→0; next palindrome by iterating n+1..∞ and comparing a number to its flipped string. Lots of concrete operators shown like divisibility operator %% and unicode sequence dots.
