Clearly it's CTFE not respecting .dup in certain circumstances.
But it behaved the same way in 2.053. In 2.052, it prints:
literal:CL_INVALID_CONTEXT
mutated:_INVALID_CONTEXT
literal:CL_INVALID_CONTEXT
because the foreach ref was simply ignored.
So it's not a regression. Instead, one form of wrong code was replaced
with another.
I'll be on holidays for the next two weeks and will not be online, so
I don't have time to fix this anyway.
