string/slice



    cfunction
    src/core/string.c on line 179, column 1

    (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.
