// - Fortran: the base symbol of the copy expression is always SHARED
// - C/C++:
// * The base symbol of a trivial copy (i.e the expression is a symbol) must always be SHARED:
// int x, a[10];
// copy_inout(x) -> shared(x)
// copy_inout(a) -> shared(a)
// * The base symbol of an array expression or a reference to an array must be SHARED too:
// copy_int a[10];
// copy_inout(a[4]) -> shared(a)
// copy_inout(a[1:2]) -> shared(a)
// * The base symbol of a class member access must be shared too:
// struct C { int z; } c;
// copy_inout(c.z) -> shared(c)
// * Otherwise, the data-sharing of the base symbol is FIRSTPRIVATE:
// int* p;
// copy_inout(*p) -> firstprivate(p)
// copy_inout(p[10]) -> firstprivate(p)
// copy_inout(p[1:2]) -> firstprivate(p)
// copy_inout([10][20] p) -> firstprivate(p)
