I am currently using this number in the middle via tostring() and
gsub(). But I'd still like to know if this can be used as an id.
This number uniquely identifies a node for as long as it stays
allocated, yes. If it is freed, a new node may have the same
number.
but for storing the node's id one can as well use the nodes user object
itself as it's equally unique during the livespan of a node and one can
compare pointers so the 'id' snippet in the string is not giving more
uniqueness than the node user object itself
