Ok, I’ve sorted it out. It’s not a bug after all, but there is a typo
in the documentation. Everything works if the restriction is (female =
0), but not with (female == 0). The documentation specifies “==” in
the “var2 op val” line & below.
I see what you mean and I actually do think it's a bug. Years ago gretl
switched from "=" to "==" as the required (or sometimes only
preferred)
equality testing operator, and this case apparently was overlooked or
got broken afterwards.
I didn’t know this feature existed before today – I think my students
will really like it!
Yeah, it's a hidden gem... (even if documented)
