I'm guessing it's because you've already got a variable holding the
store, so obviously you can just use that in the block. This is
different from say File.open where that method call is creating the
object you want to operate on inside the block that follows it. Of
course you might write a method that returns the store to you and want
to invoke a transaction on it. For example,
get_store("some-store-lookup-key").transaction do |store|
# do something with store here
end
In this case I can see where your suggestion would be nice to have.
