What a View! Building Your Own (Lazy) Range Adaptors (part 2 of 2)
summary
Implements a non‑standard lazy range adaptor called stride_view that skips elements by a user step, including a hand‑rolled iterator type, sentinel handling, and a compute_distance routine that adjusts size (e.g. every 33rd of 100 yields 67,34,1). Adds const‑qualified overloads to avoid race issues, supports front/back/subscript for common/sized ranges, composes with views::reverse, and exposes a range adaptor closure so piping works. Tests compile and pass on MSVC preview (examples and source are on the CppCon repo).
