yield
Operator
yield — emit values from expressions
Synopsis
[yield] <expr> [, <expr>...]
Description
The yield operator produces output values by evaluating one or more
expressions on each input value and sending each result to the output
in left-to-right order. Each <expr> may be any valid
expression.
The yield keyword is optional since it is an
implied operator.
