Looking at the preceding token when the lexer points to a '/'
character is insufficient to determine which context it's in. In
fact, you need to look at an arbitrary number of preceding tokens
to figure it out. This example demonstrates a case where we can
pump up the number of preceding tokens to an arbitrary size
before you can disambiguate your syntactic context.

The System loader.

var capitalize = System.get('libs/string').capitalize;
var app = System.get('app').app;

Custom loader:
