This is getting too complicated.

I dont' want to read code and pause myself 5 minutes while doing math
to understand a number.

I think that the whole point of modifying something is to simplify it.

I'm +0 on removing 0-leading literals. But only if we create "d", "h"
and "o" suffixes to represent decimal, hex and octal literals (2.35d,
3Fh, 660o). And +0 on keeping the "0x" preffix for hexa (c'mon, it
seems so natural....).
