Note handling the terminating nul is likely some off-by-one error somewhere. Handling arrays of integers (arrays in general) is harder as we do not store the constructors in target representation (same for strings written as { 'a', 'b', '\0' } btw.). One can't use the host library routines to perform the folding but has to compare two CONSTRUCTORs elementwise (they are at least sorted).
