better API to defining doubles.

[moro]

Sinatra like

inside initializer block. (in Ww::Server.build_double)
get(path, :double => :spy) do .. end

outside
Ww::Server[:server].get(path, :double => :spy) do .. end

rr like (?)

inside initializer block (in Ww::Server.build_double)
spy(self).get(path) do .. end
spy!.get(path) do .. end

outside
spy(Ww::Server[:server]).get(path) do .. end

current

inside initializer block (in Ww::Server.build_double)
spy(:get, path) do .. end

outside
Ww::Server[:server].spy(:get, path) do .. end

I'm waiting YOUR idea. Feel easy to comment, please.

[moro]

how do you think of

spy.get(:get, path) do .. end

spy() returns Proxy object to define spy(or other double) actions.
