The only wrinkle is that currently '_1' is usable name, and that should probably be disallowed if the above change took place.
Why? I've never seen a leading thousands separator in practice. For example,
,123,456
isn't generally accepted usage, so why should
_123_456
be considered acceptable?
(I'm not taking a position on the proposal here; just commenting on the problem of breaking code by making _1 a number instead of an identifier.)
I see it as a readability issue -- if you have 1_024 and _1025 (etc, etc), where one is a number and the other a name, confusion can easily result. ~Ethan~
