A fun read!

"(Late at night, I double checked. Mozilla’s CheckedInt is just as bad as I remembered. They do a division to test for multiplication overflow. Come on, put a line of assembler in there! Portability is worth a price, just not any price.)"

Shocked: do you use assembly in Checked and cripple the optimizer?!?! Luckily, no. But LDC and GDC do create the `seto` instruction I think you were hinting at:

(LDC doesn't do as good as it could, https://github.com/ldc-developers/ldc/issues/2131)
