Thank you, this definitely makes sense!
 
I remember about issue with passing/returning array in functions. By the
way I still am not sure why it works with global for example... if they
are actually different variables, every key-pair :) e.g. like here:
 
https://github.com/RodionGork/languages-benchmark/blob/main/02-primes/primes_a.tcl#L7

Because the [global] command works with names of variables, not the
actual variables.  It links the global variable with the given name, to
a local variable of the same name, inside the proc.  If the global name
references an array, then the new local name inside the proc references
the same array.
