>From the .NET docs on foreach:
The foreach statement repeats a group of embedded statements for each
element in an array or an object collection. The foreach statement is
used to iterate through the collection to get the desired information,
but should not be used to change the contents of the collection to avoid
unpredictable side effects.
My guess is that the compiler is enforcing this behavior, just as it seems
to enforce the idea that you cannot reassign a reference that it declared
inside a "using" statement (which also looks like it should be valid by
looking just at the source).
