Array.include? with a regex?

[Sergio Ruiz]

i am wondering if this is possible.. i can't seem to figure it out..

i am trying to see if a value is inside an array using regex..

something like:

a = ["pie","cookies","soda","icecream"]

i want to see if something starts with "coo" i should get one..

it doesn't look like i am doing it correctly..


irb(main):010:0> a.include?(/^coo/)
=> false

ideas?

thanks!

Enumerable#grep:

a = ["pie","cookies","soda","icecream"]
a.grep /^coo/
