- // For operators and context all the 30 remaining bit are used as an index

- // For parameters the high bits 2 to 13 are a parameter node index the 18 remaining are an index in the parameters
- // Therefore you can copy :
- // Up to 2^30 operators
- // Up to 2^30 contexts, but only the first 2^18 can have blocks with links
- // Up to 2^30 parameters, but only the first 2^18 can have nodes with links

- // Up to 2^11 parameter nodes per parameter can have links
