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.)
