I thought the OMF lib-imposed limit was about 4K. I've just made a 
template with a symbol name of 480 characters, and that was OK.
If Tuple!() works with a nesting level of 50, the limit would have to be 
pretty big.
Maybe in the future, we'll be able to add some kind of 'final' 
declaration to templates, which would indicate that they don't need to 
be stored in the object file or library, and can be discarded from the 
symbol table as soon as they are instantiated. This would be 
particularly useful for recursive templates, which can easily spew reams 
of garbage into the object file.
