Bit operations as syntax aren't coming. All numbers in Nasal are floating point, and don't mix nicely with bit twiddling. What I'm thinking about instead is a "bits" package with functions like: bits.fld(string, startbit, len) Returns the numeric value of a field of len bits starting from the indicated start bit. Bit fields are always treated in big-endian byte order (string[0] contains the highest 8 bits). bits.sfld(string, startbit, len) Same deal, but treats the bitfield as a 2's complement signed quantity and returns negative results where appropriate. bits.setfld(string, startbit, len, val) Sets the field. Doesn't need a separate version for signed vs. unsigned. bits.buf(len) Creates a new, mutable string filled with zeros. bits.swap(str) Reverses the order of all bytes in a string.
