This is in appreciation of the work Tels and many others have done to all the Math::Big* modules.

While I don't particularily consider BigInts and similar to be completely intuitive to deal with, Math::BigInt does the best it can to hide complexity using Perl's builtin facilities. I've needed arbitrarily precise and/or large numbers in some projects and would have had to switch to a completely different programming language (here: Haskell) if not for this module. Due to Tel's hard work, it's surprisingly fast, too!
