hahaha

right... but it didn't work! :D
Now I tried to figure out why...

main.rb:4:in 'each': undefined method 'self' for "a":String (NoMethodError) Did you mean? itself

as it turns out group_by(&:itself) works ;)

explain please

is it possible to search for kata using specific language?
For example if I wanted to search for Ruby kata, excluding any tranlsated ones.

thanks!
