[Gretl-devel] Defining bundle by new syntax "_()"

Hi, I stumbled over the following behavior when trying to define a bundle using the new syntax _() introduced with gretl 2020e: <hansl> scalar V1 = 0.5 scalar V2 = -0.2 bundle B = _(V1, V2) # works well print B bundle C = _(V1) # fails when only single item is added bundle D = _(V2) # fails </hansl> Ok, the doc says "The second variant is designed for the case where you wish to pack several pre-existing named objects into a bundle..." Why is _() supposed to work only with "several pre-existing named objects"? Thanks, Artur
