[IronPython] Very strange problem with ExecuteFile

Exactly. In console, each statement is compiled into its own CLR method so you won't hit this problem.

Martin,

We don't see the same problem in the IronPython console; is this because
it is executing the file somehow differently - perhaps line-by-line,
maintaining a context dictionary?
