Major slowdown in String#gsub and String#gsub! (UTF-8 input with ASCII replacement) after commit f4fd34a.
Benchmark.ips do |x|
str1 = "YWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFh\n" * 6000
repl1 = "\r\n"
x.report 'gsub ASCII with ASCII' do
str1.gsub(/\n|\r\n|\r/){ repl1 }
end
str2 = "YWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFhYWFh\n" * 6000
str2.encode! 'utf-8'

Partially applied lambdas in ruby
CleanAndCapitalize = ->(s){ s.strip.capitalize }
SplitOn = ->(delim){ ->(s){ s.split(delim).map(&CleanAndCapitalize) } }
SplitAndCleanCsv = SplitOn.(',')
CleanAndCapitalize.('BLA BLU BLI ') # => "Bla blu bli"
SplitAndCleanCsv.('BLA, BLU , BLI ') # => ['Bla', 'Blu', 'Bli']
