This thread made me think a zip iterator could be a useful addition to
the language.
def myList = [1,2,3]
def myMap = [ a:'b', c:'d', e:'f' ]
zip(myList,myMap).each { l,m -> println "$l $m" }
Prints out
1 a=b
2 c=d
3 e=f
If one collection is exhausted, whilst the other is not, then just
return 'null' for the additional items.

This also sounds like a zip operation, which took me a really long time to
find in Groovy but I recently found it:
def letters = ['a', 'b']
def numbers = [1, 2]
assert ['a1', 'b2'] ==
GroovyCollections.transpose(letters, numbers).collect { it[0] + it[1]
}
There's an easier way to use `transpose`:
assert ['a1', 'b2'] == [letters, numbers].transpose()*.join('')
Cheers,

In your case of testing a condition (equality) you can use any method
instead of collect.

Hi,
I want to know if it's possible to have a closure that can iterate over 2
equal length lists? The equivalent of doing list1.each, list2.each { ... },
where each list is a list of an user-defined type.
Basically I want to compare elements in the lists to see if they are equal.
Thanks.
Les
