Description

Desired usage:

def words = ['Ant', 'Dog']
def aWord = { w -> w.startsWith('A') }
def makeLower = { w -> w.toLowerCase() }
words.updateMatching(aWord, makeLower)

Groovy code snippet elaborating desired behavior (for a mutating version, but perhaps one that returns a modified list is the better way to go):

(0..<words.size()).each { i ->
    def w = words[i]
    if (aWord(w)) words[i] = makeLower(w)
}
println words
