Improved support for locals (stack allocation):
[@local] attribute to the t arguments of length, unsafe_set_int8, unsafe_set_int16_le, unsafe_set_int16_be, unsafe_set_int32_le and unsafe_set_int32_be.Int64.t arguments of set_int64_t_le, set_int64_t_be, unsafe_set_int64_t_le, and unsafe_set_int64_t_be.Local module providing get_int64_t_le, get_int64_t_be, unsafe_get_int64_t_le, and unsafe_get_int64_t_be functions that return local Int64.t values.New functions:
unsafe_get: retrieves character at specified position, without bounds checksunsafe_set: sets character at specified position, without bounds checksmemmem: searches for the position of a substring of needle in a substring of haystack with optional parameters for positions and lengths; returns an int optionunsafe_memmem: unsafe version of memmem function, without bounds checks
