int[] is a value with mutable indirection, so copy conversion from immutable
int[] to int[] is invalid. Then the callings of f and g with arr are solved
with no ambiguous.

But, immutable int is a value without mutable indirection, so copy conversion
from immutable int to int is *valid*. Then callings of h makes ambiguous with
the two const-conversions, immutable int -> int and immutable int -> const int.
