Ah ...

} Running 'zmodload zsh/zle' before the call appears to prevent hte
} problem.  I can do that in my callsite (z-sy-h's "make check"), but
} I assume zsh shouldn't enter an infinite loop, either.

Need to move the sanity checks out of the anonymous function.  Unless
someone suggests a variation of "return" that works like "break 2".
