->{@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)
