Issue #20433 has been updated by matz (Yukihiro Matsumoto).
IMO, this is a good chance to upgrade Hash#inspect format to adopt current Hash usage.
* symbol keys should be represented by "`key:`"
* ambiguous keys should be wrapped by (double) quotation marks
* spaces should be placed after "`:`" and around "`=>`".
I'd propose that we try new format for release candidates. If serious compatibility issues happen (although I don't believe we will see), we re-consider this change again.

Bug #20433: Hash.inspect for some hash returns syntax invalid representation
https://bugs.ruby-lang.org/issues/20433#change-109200
* 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.
