* Add a test case for that one.

Problem was simple type inlining in complex structure (like list/hash/array) is
just a hack. We are creating a subtype with the data chunk. That work with INT
or SHORT for example, but not with STRING because it's a pointer to a STRING and
not directly the STRING. This result in a double pointer dereferencing where it
shouldn't. In fact STRING is not really like other simple data type. So we
should handle it differently.

Still need to fix Array and Hash.
