This GEM allows to call methods lazily. The actual work will not be performed
until the result is used. There's no promise/force semantics, just a single
call (or block) is stored and executed the first time the (lazy) result is
accessed.
## USAGE
### simple lazy call
user = User.lazy.find(:first) # will not access a db
puts user.name # this will actually perform the find and then get the name from
# the result
### example for a lazy block
user_name = User.lazy { |user| user.find(:first).user_name } # no db access
puts user_name # db will be accessed here
## Contributing
1. Fork it
2. Create your feature branch (`git checkout -b my-new-feature`)
3. Add tests for it. This is important so I don't break it in a future version
unintentionally.
4. Commit your changes (`git commit -am 'Add some feature'`)
5. Push to the branch (`git push origin my-new-feature`)
6. Create new Pull Request
> NOTE: do not mess with rakefile, version, or history. (if you want to have
> your own version, that is fine but bump version in a commit by itself I can
> ignore when I pull)
