apologies, misunderstood.
Yes, it does:
```
(lldb) script var = lldb.frame.FindVariable("u")
(lldb) script print(var.GetChildMemberWithName('raw'))
(uint32_t) raw = 1688469761
(lldb) script print(var.GetChildMemberWithName('a'))
(uint32_t:8) a = 1
(lldb) script print(var.GetChildMemberWithName('b'))
(uint32_t:8) b = 1
(lldb) script print(var.GetChildMemberWithName('c'))
(uint32_t:6) c = 36
(lldb) script print(var.GetChildMemberWithName('d'))
(uint32_t:2) d = 2
(lldb) script print(var.GetChildMemberWithName('e'))
(uint32_t:6) e = 36
(lldb) script print(var.GetChildMemberWithName('f'))
(uint32_t:2) f = 1
```
