string/slice



    cfunction

    (string/slice bytes &opt start end)

    Returns a substring from a byte sequence. The substring is from index
    start inclusive to index end exclusive. All indexing is from 0.
    'start' and 'end' can also be negative to indicate indexing from the
    end of the string. Note that index -1 is synonymous with index
    (length bytes) to allow a full negative slice range.
