--- Comment #6 from du...@neet.fi ---
the same error message is given when taking the address of a non-lvalue, but
"cannot be modified" doesn't necessarily apply there (and can be confusing)

// Error: `a[0..2]` is not an lvalue and cannot be modified
ubyte[2] a;
const void* p1 = &a[0..2];

// Error: cannot modify constant `1`
const void* p2 = &1;

for these, the message should rather say something like "cannot have its
address taken"
