No. A small alteration to the lexical syntax for the sake of improved readability seems perfectly justifiable as long as it doesn't make the lexical syntax /significantly/ more complicated or harder to learn.
Sure. But some of us don't find it terribly readable. I think the ~~ operator hack gets 90% of the "benefit" for those who want it.
although my preference would be something a bit more restrictive, requiring numbers to have groups of the same number of digits after each â_â and beginning with a shorter group (ie 12_000_000 and 1200_0000 would be valid but 1247_000 would not). I'm not wedded to this requirement (and it would take a more sophisticated grammar to formalise).
The only reason to put it in the lexer/parser is to avoid misleading cases, which needs thas additional restriction, or something similar, like always 3 for decimal, 4 for hex, 3 for oct, or whatever. -- Aaron Denney -><-
