1. In practice, a large expression (not only a number) more often appears 
   not from a file but as  a result of a function,  a result of 
   intermediate computation.

2. A binary counter for the value of  b = 2^18  : Bin  has a small 
   representation. But the compiler still tries to evaluate at the 
compilation time the corresponding concatenation of 2^18 small lists 
built by a function in my example.
By the way, if this  b  is read from a file, will this prevent this 
long compilation effect in this example?
