GUILLAUME: "Yup: feature request or improvement."

=== HERE's WHAT I MEAN: ===

def map = ['one':1, 'two':2, 'three':3]
map.each

{key,value -> if(key=='two') println "$key:$value"}

println map.findAll

{key,value -> key=='two'}
println map.find { it.key=='two'}
println map.find {key,value -> key=='two'}
