g++ has gotten a lot better in the ~10 years since I wrote a bignum library with nested template parameters. Back when I initially did it, gcc would literally try and expand everything, resulting in insane compile times (and out of memory issues/crashes). If it did manage to compile it, the resulting exe's were also massive. At some point (to lazy to look up the flag) gcc added a template recursion parameter that stops trying to unroll everything at some sane depth. Now the code compiles quickly the .exes are reasonably sized/etc.
