{} binds more tightly than do..end so you do sometimes need to use ()
to disambiguate, eg
named_scope :foo, lambda { ... }
is ok
but
named_scope :foo, lambda do
...
end
isn't because ruby thinks that this block is for named_scope, not
lambda.
named_scope(:foo, lambda do
...
end)
makes it clear to ruby what to do.
