Best practice for methods used only during pre-initialization?

production.rb

# This simple solution permanently adds a method on Object that
# will never be used outside this file.

def compile_asset?(path)
  # ... lots of complicated logic ...
  # returns boolean
end

Foo::Application.configure do
  ...
  config.assets.precompile = [ method(:compile_asset?).to_proc ]
end

# One way to keep things clean

class <<Foo::Application 
  def compile_asset?(path)
    # ... lots of complicated logic ...
    # returns boolean
  end
end

Foo::Application.configure do
  ...
  config.assets.precompile = [ method(:compile_asset?).to_proc ]
end

class <<Foo::Application
  remove_method :compile_asset?
end

# What's a more elegant way?

Does compile_asset? ever use anything other than the path parameter? If not, then you could just move it inline:

Foo::Application.configure do
  ...
  config.assets.precompile = [ ->(path) {
    # lots of complicated logic ...
    # returns boolean
  } ]
end

@rahearn suppose if you will the precompile method calls two other methods that each encapsulate a bit of file-matching logic.

I'm probably wrap them all in a module that sticks around but then doesn't leak out into Object.
