Raku_topic_var

I like the default variable $_.. the ‘Topic variable’.

.say for <olle nisse janne pelle kalle>;

for enumerates through the list. Every element in order is assigned to $_. The empty .say is interpreted as $_.say. In Ruby it would be the same as not having to type it.

%w(olle nisse janne pelle kalle).each { puts }

You can do something similar in Ruby:

class String
  def say = ( puts self )
end

%w(olle nisse janne pelle kalle).map(&:say)
