Bug #15786: numbered parameterを使ったprocのparametersに記号が現れる
https://bugs.ruby-lang.org/issues/15786

* Author: tompng (tomoya ishida)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.7.0dev (2019-04-23 trunk f4f66bd11c) [x86_64-darwin17]
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
~~~ruby
->{@100}.parameters.map{@2}.join
#=> "!\"\#$%&'()*+,-./:;<=>?@[\\]^`"
~~~

`proc{@100}.parameters` の場合はそれに加え、`[[:opt, nil]...]` になる

`RubyVM::InstructionSequence.of(->{@100}).to_a`
`RubyVM::InstructionSequence.disasm(->{@100})`
にも同様の記号が混ざる

`lambda{@100}.parameters` は `[[:req]]*100`
`proc{@100}.parameters` は `[[:opt, nil]]*100`ではなく`[[:opt]]*100`
になると良いのではないかと思います。(`1.method(:+).parameters #=> [[:req]]` とnilは含まれないのでそれに合わせて)
