Would 0X12 then be a 12-bit integer with the value zero or a hexadecimal `int` literal with a base-10 value of 18? Does this work for other bases (0X12X12)? I'm not sure why they picked a letter which can already occur in integer literals rather than one of the many unused letters. Given the focus on FPGAs and HDL it's also worth noting that X is commonly used in binary or hexadecimal constants in HDLs to denote undefined or "don't care" values, which could lead to confusion. Rust integer literal syntax would be perfect here (1234u11 or 1234i11) since it already includes the bit width and is compatible with any base prefix.
