Agreed. If the || issue with lambda was fixed, couldn't that read: named=5Fscope :recent, lambda{|time =3D 2.weeks.ago| {:conditions =3D> ["released=5Fat > ?", time]} } There is only a 3-character difference in typing, but if that is too much, here are a couple 1-character options. # Use &func like Perl named=5Fscope :recent, &{|time =3D 2.weeks.ago| {:conditions =3D> ["released=5Fat > ?", time]} } # Use \{}=20 named=5Fscope :recent, \{|time =3D 2.weeks.ago| {:conditions =3D> ["released=5Fat > ?", time]} } =20 # Use coupled {{ }}=20 named=5Fscope :recent, {{|time =3D 2.weeks.ago| {:conditions =3D> ["released=5Fat > ?", time]} }} Nate Wiger PlayStation --=_alternative 005BFC8D88257452_= Content-Type: text/html; charset="ISO-8859-2" Content-Transfer-Encoding: quoted-printable

Agreed. If the || issue with lambda was fixed, could= n't that read:

named=5Fscope :recent, lambda{|time =3D= 2.weeks.ago| {:conditions =3D> ["released=5Fat > ?", time]} }
There is only a 3-character difference in typing, but if that is too
much, here are a couple 1-character options.<= /tt> # Use &func like Perl named=5Fscope :recent, &{|time =3D = 2.weeks.ago| {:conditions =3D> ["released=5Fat > ?", time]} } # Use \{} named=5Fscope :recent, \{|time =3D 2.we= eks.ago| {:conditions =3D> ["released=5Fat > ?", time]} } # Use coupled {{ }} named=5Fscope :recent, {{|time =3D 2.we= eks.ago| {:conditions =3D> ["released=5Fat > ?", time]} }} Nate Wiger PlayStation --=_alternative 005BFC8D88257452_=--
