class RuboCop::Cop::Performance::MethodObjectAsBlock
This cop identifies places where methods are converted to blocks, with the use of `&method`, and passed as arguments to method calls. It is faster to replace those with explicit blocks, calling those methods inside.
@example
# bad array.map(&method(:do_something)) [1, 2, 3].each(&out.method(:puts)) # good array.map { |x| do_something(x) } [1, 2, 3].each { |x| out.puts(x) }
