Why do sinatra/main requires sinatra/base?

[agis]

I know that a Sinatra app can be built using the Classic or the Modular style, meaning that it will require sinatra for the former and sinatra/base for the latter.

But I was wondering, why does sinatra/main.rb requires sinatra/base?

This is certainly not needed when you're using the Classic or the Modular way, cause in each case this file is loaded either via sinatra.rb (classic) or directly (modular).

I imagined that this was the case because a module is meant to take care of its own dependencies. In the case of Sinatra/main, that dependency is Sinatra/base. In the case of Sinatra.rb, those dependencies are both base and main.

There's no harm in having a double require: require's smart enough to recognise that a file has already been required and won't re-require.

That was my assumption, anyway!
