Thank you ! I completely missed isSomeString.

I think the definition can be safely shortened to:
bool hasItemParent(T)(const(char)[] itemId, T parentId)
if (isSomeString!T || isSomeString!(ElementType!T))

Minor flaw, as it is the function also accepts wchar[] and 
dchar[] that break the compilation because I do comparisons with 
char[].
