Re: [Gretl-devel] nesting a function call getting a list doesn't work / Re: getenv(): about environment strings

There are some built-in gretl functions that return lists. These have the potential of overwriting data series previously created by the user, but (I think) they are quite explicit regarding the names of the series they create and return. Caveat emptor. I wouldn't necessarily trust a contributed function that returned a list unless I knew the author well. IMO that's not a reason to stop using lists. But I think it _is_ a reason to resist Sven's suggestion that the error resulting from giving an anonymous, on-the-fly, function-returned list as a function argument is a gretl bug. I thought it was a bug, at face value, but now I don't think so; I believe it's a defensible safeguard. However, the resulting error message should be clearer. Allin
