----------------------------------------
Bug #20337: Complex#inspect mutates the string returned by `real.inspect`
https://bugs.ruby-lang.org/issues/20337
* Author: Eregon (Benoit Daloze)
* Status: Open
* ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux]
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
```
irb(main):001:0> n = Numeric.new
=> #<Numeric:0x00007f81b2308578>
irb(main):004:0> class Numeric; def inspect = super.freeze; end
=> :inspect
irb(main):006:0> Complex(n, 1).inspect
(irb):6:in `inspect': can't modify frozen String: "#<Numeric:0x00007f81b2308578>" (FrozenError)
from (irb):6:in `<main>'
from /home/eregon/.rubies/ruby-3.2.2/lib/ruby/gems/3.2.0/gems/irb-1.6.2/exe/irb:11:in `<top (required)>'
from /home/eregon/.rubies/ruby-3.2.2/bin/irb:25:in `load'
from /home/eregon/.rubies/ruby-3.2.2/bin/irb:25:in `<main>'
```
It feels wrong to mutate the result of inspect at least in general, for instance `true.inspect` is frozen.
