it would be very useful to get the size of data stored in some hash-table without having to read the data into a string previously.
' currently have to dim a string:
Dim sData As String = Hash_Get(pHash, sKey)
' and then determine size of data:
Dim lDataSize As Long = StrPtrLen(StrPtr(sData))
Dim lDataSize As Long = Hash_Len(pHash, sKey)
could be Hash_Size as well - but i think this could lead to some confusion since the user might think it's to determine total size of a hash-table
