Yes, that seems eminently reasonable to me. I'm not whining about that.

It's not my consistency check.

It's calling 'AllowSubstExceptions()' that causes the issue. And either I have to set up subst_dict or I have to clone the environment and switch that off, neither of which seems very nice

I think when I have time I'll dig a little further into this because the code certainly looks like it should work, and the caller doesn't set up LINESEPARATOR either so I don't really understand why that doesn't cause a problem.
