No. Some tk widgets map their values to Tcl variables. Other similar  
interfaces exist. It is handy to map them to an instance variable but  
for that it is necessary to have the namespaced version available. Of  
course you could always do it through globals, but that is just more  
messy.

I think something similar was making its way into Tcl?

I've seen it happen with scripts given to [after]. I was actually  
very surprised by this, but at some point I was witnessing those  
scripts becoming strings and thus losing the original Tcl_Objs inside  
them (the scripts were built as lists).
