I wish we stayed with the hash rockets, sigh

Bug #20433: Hash.inspect for some hash returns syntax invalid representation
https://bugs.ruby-lang.org/issues/20433#change-109216
* Author: tompng (tomoya ishida)
* Status: Open
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
For these hashes, Hash.inspect returns a syntax invalid representation:
~~~ruby
{ :a! => 1 } # {:a!=>1}
{ :a? => 1 } # {:a?=>1}
{ :* => 1 } # {:*=>1}
{ :== => 1 } # {:===>1}
{ :< => 1 } # {:<=>1}
~~~
`eval(hash.inspect)` will raise SyntaxError.
Although inspect does not guarantee that the result can be eval-ed, it'd be confusing for these few cases.
