可以将以下Perl代码简化为一个语句：
my $a = 'hello'; my $b = $a; $b =~ s/o//;
我的$ a ='你好';我的$ b = $ a; $ b = ~s / o //;
I am looking for something like:
我正在寻找类似的东西：
$b = $a =~ s/o//;
$ b = $ a = ~s / o //;
(although that does not produce what I want; $b becomes "1" or "true")
（虽然这不会产生我想要的东西; $ b变成“1”或“真”）

($b = $a) =~ s/o//;
