Maximum capacity of a TUPLE

[Colin Adams]

The header comment to {TUPLE}.plus says the result can be Void if the result exceeds the capacity of a TUPLE. What is this maximum capacity? 

(without knowing it is is impossible to prove the result of such a concatenation will be attached).

[Emmanuel Stapf]

If you are looking at TUPLE with more than 20 entries, I think I would consider using LIST or ARRAY for storing data.

 

The issue is not so much on the TUPLE capacity (which has the same limit as a SPECIAL object) but on the number of class types any  type declaration. This is a limit for all types, not just for TUPLE. For example: HASH_TABLE[ TUPLE [LIST [ANY]], STRING] has 5 types. That number is the limiting factor in a type declaration and the runtime only handles at most 256 of them in a declaration.
