Ah, my mistake. I skimmed the method names several times looking for
"bundle" or "clone" (but not that one) or "group" (but not that one)
or "parenize", but didn't see #from_self. I should have read the full
description of each method.
Which of the following implementations do you prefer:
# Option 1 - change one line from current
def from_self( aliaz=nil )
fs = {}
@opts.keys.each{|k| fs[k] = nil}
clone(fs).from( aliaz ? as(aliaz) : self )
end
# Option 2 - standalone
def from_self( aliaz=nil )
if aliaz
@db.dataset.from(as(aliaz))
else
fs = {}
@opts.keys.each{|k| fs[k] = nil}
clone(fs).from(self)
end
end
