Introduced 'string.slice' Object
Since 0.23.8 version it is possible to use
string.slice
object just like this:
"Привет".slice 1 2
Here, slice object returns “ри” string, which is a substring of “ри” string
from the specified start position and with the length len.
If above parameters will be out of bound, slice will return
an error object instead of a new string object.
