The rule is that a short variable declaration requires that at least one
non-blank variable is new (the specification even says so) Consider
_, y := 4,5
where one variable, y, is new. In
_ := 6
or
_, _ := 5, 7
this rule is violated, since there are no non-blank variables (and thus
vacuously nothing new).
I think the reason this is a rule is because it may detect some spurious
errors by forcing the programmer to write code in a certain style, but I
may be wrong.
