That's what's happening.

But I feel it's a bug, or at most misfeature.  eval() should execute
as if the evaluating string is embedded in the code, so that the error
in this case is not what I expect.  But I found it's pretty hard to
fix.  It will remain as it is until I reimplement the core in the
future version.  Sorry.
