sorry ^^

maybe too complex :D sorry
haha

i disagree with .map(&:eval) advice. "[1,2,3]".eval will trigger an NoMethodError

Can you explain your solution?

Thanks voile, instructions updated

dashs '-' and underscores '_' are considered as word separators

only letters and digits are allowed, the rest must be removed

What about words with other characters mixed in alongside letters and digits? How are they supposed to be handled?

What if the first letter of a word is a digit? What if the first letter of every word is a digit?

Also, how are non-letter and digits removed? Before or after split? These are all unclear from the description.

thx for your time, i hope you enjoyed it ^^
