[datatable-help] "Within" Reversed column order?

[Yike Lu]

I noticed this when I moved from chained [,:=] to within...

When adding columns, the columns are added in reverse order of the
assignment order, e.g.

DT= data.table(a=1:10, b=2:11)

within(DT,
{
c=a*b
d=a+b
}
)

# d appears before c in the column ordering.

While this isn't a huge deal, it is annoying as I often create data.tables
with many columns and the ordering is intentional, to make the data easier
to read.

Is this a bug?
