Refinements take place at block passing

[headius]

See https://bugs.ruby-lang.org/issues/14223

using Module.new {
	refine String do
		def to_proc
			proc { |it| it.send self }
		end

		def refine_method
			"X#refine_method"
		end
	end
}

def func &block
end

p "upcase".refine_method
# => "X#refine_method"

p "upcase".to_proc.call "homu"
# => "HOMU"

# Error: wrong argument type X (expected Proc) (TypeError)
func &"upcase"

The final line should work, but raises. We don't handle this because the to_proc call is happening inside CallNode logic, with the string being passed as the block operand. We should move the to_proc call outside of the invocation so it can cache and inline and all.
