Hello,

You're a real human debugger ;-)

Could you please fill a JIRA request in our bug tracker?

Thanks in advance.

See some comments below:

I also get that error, whether it be in the interactive shell in on
the command-line:

groovy> a = 1
groovy> b = "foo"
groovy> for (keyval in binding.variables) {
groovy>     println "${keyval.key} = ${keyval.value}"
groovy> }
groovy> go
a = 1

So, please put that in JIRA so that we don't forget about it. And I
hope we'll fix it quickly.

Thanks again for your patience, and sorry for any inconvienience.
