Right, you would still need the parentheses. But note that the second
syntax (with the "->") would always be wrong. The "::" syntax just says
"find this name not in the current namespace, but in this absolute
namespace I am giving you". But "X->Y" is actually a syntactic shorthand
for "look up X::Y (or Z::Y, where Z is the blessed package of X), and
then call X::Y(X, @_)".
Which makes sense for object-oriented stuff. You get the object or the
classname as the first parameter to a method. But for a regular package
function, you would be calling
Term::ReadKey::ReadKey('Term::ReadKey', 0)
which of course makes no sense.
But I think doing the import makes more sense (and is how Term::ReadKey
is intended to be used), so the patch you posted is best.
