Is the &method(:method_name) idiom bad for performance in Ruby?

I've recently come across the &method(:method_name) syntax. (This uses the Object#method method - RDoc link) For example,

[5, 7, 8, 1].each(&method(:puts))

is the equivalent of

[5, 7, 8, 1].each{|number| puts number}

Are there performance penalties for the latter compared to the former in the various implementations of Ruby? If so, are the implementors working on improving its performance?
