Tony,
Note that when you set a variable to a proc value, the value does not
get evaluated immediately--rather, it gets evaluated the first time
the variable is referenced. What you probably want is just this:
set :password, Capistrano::CLI.password_prompt("...")
set :intranet_login, Capistrano::CLI.password_prompt("...")
set :intranet_password, Capistrano::CLI.password_prompt("...")
Also, note that when setting a proc-valued variable, the preferred
syntax is this:
set(:password) { ... }
Using the proc keyword, or even Proc.new, is just ugly, IMO. :) Avoid
it whenever you can.
