为什么Perl不支持双引号内的散列插入？它支持标量（$），数组（@）的插值，那么为什么不用于散列（％）呢？解析方案
散列stringify？标量是显而易见的，也是数组。但是散列应该是什么？这样的字符串化会有多大用处？它是否比使用插值字符串中未转义的％字符更有用或更少？是否值得花费大量的工作来修复今天在插入字符串中使用％的所有代码？
如果您能对这些问题提出良好的答案，那么我相信P5P会愿意听他们的。
#!/usr/bin/perl
use warnings;
my %hash=("no1"=>1,
"no2"=>2,
);
print %hash; #Prints no11no22
print "%hash"; #Prints %hash
Why doesn't Perl support interpolation of a hash within double quotes? It supports interpolation for scalars ($), arrays (@) then why not for hashes (%)?
How should a hash stringify? Scalars are obvious and arrays too. But what should a hash be? How useful will such a stringification be? Is it more or less useful than being able to use a % character unescaped in an interpolating string? Is it worth the amount of work it will take to fix all of the code that uses % in interpolated strings today?
If you can come up with good answers to these questions, then I am sure P5P would be willing to listen to them.
