Description

Groovy apparently tries to guess whether you're going to use a loop variable after a for loop ends. There is a bug in the case that you have another for loop that tries to use the same loop variable later. For instance:

for (i in 0..7) {
}
println i
for (i in 0..7) {
}

Groovy produces

loop.groovy: 4: The current scope does already contain a variable of the name i
@ line 4, column 1.
for (i in 0..7) {
^

1 Error

If the println i is commented out, the program runs.
