4.If the selected case is a RecvStmt with a short variable declaration or an assignment, the left-hand side expressions are evaluated and the received value (or values) are assigned. 如果所选case是具有短变量声明或赋值的RecvStmt,则评估左侧表达式并分配接收值(或多个值)。 5.The statement list ...
If the selected case is a RecvStmt with a short variable declaration or an assignment, the left-hand side expressions are evaluated and the received value (or values) are assigned. The statement list of the selected case is executed.
