tail
Operator
tail — copy trailing values of input sequence
Synopsis
tail [ <const-expr> ]
Description
The tail operator copies the last N from its input to its output and ends
the sequence thereafter. N is given by <const-expr>, a compile-time
constant expression that evaluates to a positive integer. If <const-expr>
is not provided, the value of N defaults to 1.
Examples

"foo"
[1,2,3]' \
