When you do
elem.attrib = value
In IupLua
Is more or less the same as
iup.SetAttribute(elem, "ATTRIB", value)
But if value is a Ihandle, the metamethod in Lua will automatically finds
the name or even assign a name to an Ihandle and set that name as attribute
for you. So you don't have to do that.
For IupGetParam you will have to do that inside the callback where you
will be able to access the internal dialog handle used by IupGetParam.
Answering your question it is possible to get a name of an element (if it
has any) using iup.GetName()
