Name lookup not working on iterators of record type

[perost]

Description

Looking up a field in an iterator of record type does not work.

Steps to Reproduce

Trying to instantiate a model such as this:

record R
  Real x;
end R;

model M
  R r[3];
  Real x[:] = {i.x for i in r};
end M;

gives the error:

Error: Variable i.x not found in scope M.

Expected Behavior

The model should work, since it's allowed for an iterator to be of record type.
