But, I'm pretty sure that this is talking about a block which is
passed as an argument to should_change/should_not_change as in this
example from the docs:
string = "string"
lambda {
string.reverse
}.should change { string }.from("string").to("gnirts")
as opposed to:
string = "string"
lambda {
string.reverse
}.should change do
string
end.from("string").to("gnirts")
This is because do/end binds less tightly than {} so that in the first
(working case) the block is passed to the change method, while in the
second one it gets passed to the should method instead.
On the other hand:
string = "string"
lambda do
string.reverse
end.should change { string }.from("string").to("gnirts")
should work, although I prefer the {} syntax in this case.
