I entered "x(i) = y(i) + z(i)" in the online demo, all three sparse, and I noticed some useless variable definitions: int32_t iz0 = z1_idx[pz1];

Is this intentional? (if so, why)




We’ve tried to engineer it to emit clean code, but seems we left in some unused variables.

The C compilers dead code elimination should remove those though.
