Couldn't agree more with the reasoning (as per the last time). One
thing that has been circulating around my mind is an aliasing "it"
with "he", which makes a lot of sense when you write specs from a
User's perspective:
describe "A", User do
he "should receiving an extra 2 dollars when he passes go"
end
Anyway - would it be reasonable for this to go into rspec core? It
seems too specific to *my* needs, and not central enough to specs in
general. Plus, if this were added, should "she" also be added?
Just another thing - I've never understood why so many find lambda to
be an unusual construction - a block *is* a lambda, and it *is* a
Proc (more or less), and those are used everywhere in the language.
