It means without bonds when assigned to a variable, and when you see it sitting pretty in the middle of a long sentence.

And it does not represent that. You can represent any number with double or simple precision, only, well, you'll lose some precision. > Oh my goodness gracious did you top yourself with Perl 6.

Or using Inf exactly by its meaning, "larger than anything". How do you do that in other languages? You do all kind of things. You can have a special constant, use 0 or -1 as limit (or some other impossible number which you have to interpret ad hoc), or simply have different signatures for with or without limits. How's that any simpler than using Infinity meaning no limits, and always meaning no limits? Perl 6 makes writing programs meaningful and expressive. That's achieved through clever language design, such as this simple thing. Cheers JJ
