Ruby can only parse 2498 case statement branches

case_test.rb

case_statements = 10000
program = <<-RUBY
case(ARGV[1])
#{case_statements.times.map { |n| "when #{n+1} \n  puts #{n+1}"}.join("\n")}
end
RUBY

File.write('test.rb', program)
puts "RUBY_VERSION=#{RUBY_VERSION}"
puts system('ruby test.rb')

=begin
$ ruby case_test.rb 
RUBY_VERSION=3.1.2
test.rb:4997: nesting too deep
  puts 2498
