[erlang-questions] Question about receive

[Jani Launonen]

Hello,

how about erlang:make_ref()?

 From the online manuals (http://www.erlang.org/doc/man/ 
erlang.html#make_ref/0)
"make_ref() -> ref()
Returns an almost unique reference.

The returned reference will reoccur after approximately 2^82 calls;  
therefore it is unique enough for practical purposes.

 > make_ref().
#Ref<0.0.0.135>"

Hope this helps.
Jani L
