[Gretl-devel] exists() vs. inbundle()

Hi, I'm wondering what the value added of 'inbundle' over 'exists' is. In principle both check for the existence of an object and return a type code if yes. I know that currently where inbundle(b, "m") returns 0 because m isn't there, exists(b.m) instead yields an error. But I guess that could be changed if wanted. And vice versa: inbundle(a, "x") yields an error if there is no bundle a, whereas exists(a.x) just returns 0. But are those differences really by design or just by historical coincidence? thanks sven
