[datatable-help] changing data.table by-without-by syntax to require a "by"

[Sadao Milberg]

I'd agree with Eduard, although it's probably too late to change behavior now.  Maybe for data.table.2?  Eduard's proposal seems more closely aligned with SQL behavior as well (SELECT/JOIN, then GROUP, but only if requested).
