为什么在没有块的情况下调用 eval 会终止这个 Perl 程序?

Why does calling eval without a block terminate this Perl program?

以下程序在第二次调用 eval 时停止。这是预期的吗?我阅读了 perldoc -f eval 并惊讶地发现 print "2: ..." 的输出没有显示。

eval {die("The curly braces seem to rescue me! Life moves on")};
print "1: $@\n";
eval die("Program actually terminates here! Subsequent prints are not shown");
print "2: $@\n";

perldoc -f eval

eval EXPR
eval BLOCK
eval    In the first form, often referred to as a "string eval", the
        return value of EXPR is parsed and executed as if it were a little
        Perl program.

... 所以 die 被调用,然后字符串 it returns 被求值。

… 除了它不是 return 字符串。它使程序死掉,所以 eval 永远不会被调用。
