This is expected behavior.
'alias this' works as proper super type.
struct S { T[] data; alias data this; }
In this code, S behaves as it is derived from T[] .
Following to this view, the definition of opIndex in S
overrides (and
hides) T[]'s opIndex completely.

How do you overcome this, in the case where you don't know the
data type of 'data' (so you don't know what the overloads
might look like, maybe because it's a template)?
Not quite sure what you mean, but
auto opIndex(A...)(A a) { return data[a]; }

What if it's const/pure/@safe/whatever though? Or the parameters
have some attributes?
(I guess this is a more general problem than opIndex
specifically, though.)
