# Buffer length operator
The length operator # applied on a Buffer object returns the total number of bytes it contains.
Example
local buff1 = sys.Buffer { 97, 98, 99 } -- "abc" in utf8
local buff2 = sys.Buffer { 100, 101, 102 } -- "def" in utf8
local concat = buff1..buff2
-- outputs 6
print(#concat)
