Is this the intended design? Is there a workaround which allows me to
ensure that the parameter is exactly 2 length?
Actually an array literal's default type is a slice, not a fixed-sized
array. With IFTI, the type is decided by the call, not how you use it the
parameters.
I filed an enhancement request a while back that would help fix this.
