I can run multiples algorithms in parallel using the tree at the same 
time and its thread safe.

If the tree doesn't change, yes, it is immutable

:-)

If no thread modifies the tree, it is thread safe since the data is 
parallel.

But if you run an algorithm, is to find out something about the data 
isn't it? How do you add information to a const tree? Difficult.

Yes, you can do a separation between added data (calculated) and 
original data (const).

Or, you do not modify the tree and rebuild a new non const tree with the 
new calculated data for each node.

The type is no longer const since you can have either a const or non 
const tree of the same shape.

There are many solutions and what is important is to try to be aware of 
the practical problems, the compiler and the computer language used are 
just aid/nuisance whatever.
