Because of compatibility constraints, JS history can generally proceed only
in an additive manner, which means a steady degradation of quality along
the "simplicity" dimension. An opt-in mode switch is the only way to escape
that dynamic. Strict mode is the only one we've got, and the only one we're
likely to have in the foreseeable future. Strict mode should not accept
octal literals. Regarding sloppy mode, it continues to exist only for the
sake of legacy compat, so adding more crap to it for better web compat is
the right tradeoff -- as long as the crap stays quarantined within sloppy
mode.

In section 11.8.3 (Numeric Literals), the definition for
`DecimalIntegerLiteral` should somehow be tweaked to match that of
`DecimalDigits`, with the exception that if the first digit is `0` and all
other digits are octal digits (0-7) it must be treated as a legacy octal
literal.
So this horrible footgun, changing the value of a constant
changes its radix, is only lurking in sloppy mode.
