### What would you like to be improved?
The CLI can support parsing of more complex types e.g. maps contain maps or
lists.
Here are some tests to help:
```
@Test
public void testParseTypeNestedList() {
Type type = ParseType.toType("list(list(integer))");
assertThat(type, instanceOf(Types.ListType.class));
Type innerList = ((Types.ListType) type).elementType();
assertThat(innerList, instanceOf(Types.ListType.class));
Type elementType = ((Types.ListType) innerList).elementType();
assertThat(elementType, instanceOf(Types.IntegerType.class));
}
@Test
public void testParseTypeMapWithNestedValue() {
Type type = ParseType.toType("map(string,list(integer))");
assertThat(type, instanceOf(Types.MapType.class));
Type keyType = ((Types.MapType) type).keyType();
Type valueType = ((Types.MapType) type).valueType();
assertThat(keyType, instanceOf(Types.StringType.class));
assertThat(valueType, instanceOf(Types.ListType.class));
Type elementType = ((Types.ListType) valueType).elementType();
assertThat(elementType, instanceOf(Types.IntegerType.class));
}
```
### How should we improve?
Not while this might seem at first complex, it is very simple to do and only
requires changing a couple of lines of code.
