Example for errorneous import behaviour

when using a class only in a switch/case branch it seems, that its import gets lost.

setup

Clone this project and run npm install and compile the ts files via atom typescript plugin.

run tests

run npm test to see the errorneous behaviour.

In case a class is only referenced in a branch(, as you can see in the Vehicle class), of a switch/case statement it seems, that its require statement is not pushed inside the file.

By referencing the class e.g. also in a console.log() statement as shown in the Car class, the import becomes visible.

Vehicle
  #constructor()
    ✓ should have a gasoline engine by default
    1) should have a diesel engine when set

Car
  #constructor()
[Function: DieselEngine]
    ✓ should have a gasoline engine by default
[Function: DieselEngine]
    ✓ should have a diesel engine when set


3 passing (13ms)
1 failing

1) Vehicle #constructor() should have a diesel engine when set:
   ReferenceError: DieselEngine_1 is not defined
    at new Vehicle (dist/Vehicle.js:7:35)
    at Context.<anonymous> (test/test.js:13:29)

When using the tsc command line utility all works as expected.
