"With LSP, you don't have to configure for every language!"
"If you're not using LSP, go use it!"
It works with every language, every OS, in Vim8 or Neovim...Great!
He talks about vim so passionately, that's awesome.
He says "Go use it!" so many times, I'd like to use LSP more!

Weird rubygems error by redefining `find` method

Here, with broken_find.rb required, specification.rb raises an error saying stub is an Array.

/Users/okuramasafumi/.rubies/ruby-2.6.1/lib/ruby/site_ruby/2.6.0/rubygems/specification.rb:1065:in find_active_stub_by_path': undefined method this' for #<Array:0x00007fc3e18ff960> (NoMethodError)

The error disappears with working_find.rb required.

The only difference is whether ifnone.call if ifnone exists or not.

However, in specification.rb uses find method without ifnone argument. This means ifnone is nil.
