There isn't a practical 8-bit integer type in C, so the smallest integer you can get is "short", i.e. 15 resp. 16 bits. For line numbers, 65536 seems a little too restrictive, so 31 bits is the next-larger type. > If python is being used as an intermediate language (code is > automatically generated, and not read by humans), then I don't see any > justification for any particular limits, except as an implementation > detail driven by convenience. Precisely so. The main point is that we should set a limit, and then code according to that limit. There is no point to use a 64-bit integer for code size constraints.
