David Baelde commented on LS-501:
---------------------------------
Good catch concerning video_text.ml! It's also a good idea to install a
protection against such problems, I should have thought about that last time I
hacked one by hand to debug...
The position of the allow_lazy_config_eval in main.ml isn't so strong: it only
protects against the forcing of the lazy values done before command-line
parsing. But that's enough for bugs such as the one you spotted, where the
value is used as the default for some operator's parameter. And I don't see a
better solution anyway... it seems impossible.
Minor remark: I'd prefer a allow_lazy_config_eval of type unit -> unit, to
signify that once it's been allowed it doesn't make sense to disallow it.
Also there's a typo: "before the user gets a chance to override" without an
"s", in frame.ml and mli.
