Like with:
irb(main):025:0> 10.times.map {|i| next if i == 2;i*10}
=> [0, 10, nil, 30, 40, 50, 60, 70, 80, 90]
"next" is for a block about the same as a "return" for a method: the
current call is terminated at this point with the provided arguments
given to the caller (the "yield"). And since "next" is a keyword it
does make sense to have it follow the same syntax rules for arguments
like "return" and "break".
Hans, thank you for the heads up!
Kind regards
robert
