This commit introduces a functional Path AST visitor and implements
`each` on the AST in terms of the functional visitor. The functional
visitor doesn't maintain state, so we only need to allocate one of them.
Given this benchmark route file:
```ruby
require 'action_pack'
require 'action_dispatch'
route_set = ActionDispatch::Routing::RouteSet.new
routes = ActionDispatch::Routing::Mapper.new route_set
ObjectSpace::AllocationTracer.setup(%i{path line type})
result = ObjectSpace::AllocationTracer.trace do
500.times{|i|
routes.resource :omglol
}
end
result.find_all { |k,v| k.first =~ /git\/rails/ }.sort_by { |k,v|
v.first
}.each { |k,v|
p k => v
}
```
node.rb line 17 was in our top 3 allocation spot:
```

```
This commit eliminates allocations at that place.
[skip ci].
- Update to the current output when running `byebug help`.
- Remove the alias `exit` because it does not work and seems to have
been removed from Byebug, as confirmed by the source code here:
https://github.com/deivid-rodriguez/byebug/blob/master/lib/byebug/comman
ds/quit.rb
- Added the useful `q!` instead to avoid the "Really quit? (y/n)"
prompt.

Better reading flow for the information presented in this guide.
The first part is written in a similar fashion as the "Getting Started
Guide" and can be read from start to finish. The second section
introduces the different testing components that Rails provides and
explains how and when to use them.
The guide is still work in progress.
The semantic versioning specification uses MAJOR.MINOR.PATCH – it would
make more sense to set the version to 0.1.0 for initial development
since a patch release cannot be created before a minor feature release.
* Add missing `def` and remove useless `do` keywords.
* Move `:nodoc:` in front of the methods' definition so that methods
under these ones are correctly visible on the API.
I would like to change the signature of the Route constructor. Since
the mapping object has all the data required to construct a Route
object, move the allocation to a factory method.
We should build the routes using the user facing API which is `Mapper`.
This frees up the library internals to change as we see fit. IOW we
shouldn't be testing internals.
Oops, I broke the build :(
Fixes the method signature of `assign_parameters` which now takes 6
arguments instead of 4. We likely will end up chaning the method
signature further so good to know this test is here.
This is part of a larger refactoring on controller tests. We needed to
move these methods here so that we could get rid of the `|| key ==
:action || key == :controller` in `assign_parameters`. We know this is
ugly and intend to fix it but for now `generate_extras` needs to be used
in the two methods to access the path and the query_string_keys.
We're adding `:controller` and `:action` to the `query_string_keys`
because we always need a controller and action. If someone passed
`action` or `controller` in in there test they are unambigious - we
know they have to go into the query params.
this removes the following warning:
```
DEPRECATION: `config.poll_interval = 0.5` will be removed in Sidekiq 4. Please update to `config.average_scheduled_poll_interval = 0.5`.
```
