... you get the general idea, though: that with sz and SNZ there's a
way for predicate masks to interact with the CR Vector, to create
Vec-AND and VEC-OR behaviour  that, at the same time, still allows CTR
the option of counting masked-in elements or all elements.

also, early-exit has the "truncate VL" option, so that, hmm, i just
realised, that could help with strncpy and strlen.

feel free to help edit and correct the syntax errors.
