spec: apparent contradiction for passing of slice argument to variadic parameter #30769
Description
Version of November 16, 2018
Section "Passing arguments to ... parameters" says:
If the final argument is assignable to a slice type []T, it may be passed unchanged as the value for a ...T parameter if the argument is followed by .... In this case no new slice is created.
Notice the use of the word "may". This appears to contradict what I understand to be the case in practice (i.e. that it will be passed unchanged, for reasons of efficiency) but also the example that follows:
... who will have the same value as s with the same underlying array.
Notice the use of the word "will".
