You are mistaken. We were talking about the maximum value that can be used in a range, and it's not even close to 2**50.

(By the way, the largest positive integer that can be stored without loss of precision in a double-precision float is 2**53.)

I was wrong too, though. I thought it was the largest native unsigned integer, but it's the largest native signed integer. 

$ perl -e'1 for 2147483647..2147483647'

$ perl -e'1 for 2147483647..2147483648'
Range iterator outside integer range at -e line 1.

That limit be obtained using the following: 

use constant MAX_RANGE => (~0)>>1;
