Allow CJS-style AMD to execute in require-order.#1484
Conversation
Traditionally AMD executes all dependencies before executing a module. CommonJS, on the other hand, executes in require-order. That is, require determines the execution order. When transpiling CJS to AMD this can cause a problem where a module written for CJS that contains a circular dependency where it depends on require execution order can break. This change allows for CJS-style AMD modules to execute in require-order. There is a flag in Steal, `executingRequire` that triggers this. We turn this flag on in a CJS-style AMD module, and only execute dependencies up front, if those dependencies are listed before the first `exports`, `module`, or `require` dependency. Closes #1483
