* Remove whitespace generation and rely on default printing
Changes to printing:
* Add newline after last empty SwitchCase
* Add newlines around block comments if they are non-flow comments or contain newlines
* Fix a few more fixtures
Previously, all "bare imports" (e.g. `import './foo';`) were moved to the
end of the array of sources. I presume this was done to remove needless
variables in the callback signature.
Unfortunately, doing this actually changes the intent of the program.
Modules should be evaluated in the order that they were in the source.
In the case of a bare import, it is quite possible that the bare import
has side effects that a later required module should see. With the current
implementation the later imported modules are evaluated before that "side
effecty" module has been evaluated.
Obviously, it is better to avoid these sorts of side effect ridden modules
but even still you could imagine a similar issue with cycles.
This change ensures that module source order is preserved in the AMD
dependencies list, and avoids making needless variables as much as possible.
* Fix buildExportAll to account for commonjs/amd
If the re-exported module was generated with Babel and it is a commonjs or amd module and so is the current module, this will result in an attempt to redefine the __esModule property, which throws a runtime error.
* Add test: don't overwrite __esModule on re-export
(Failing.)
* fixup tests
* Add fix for systemjs
The untransformed `let` keyword causes problems for older parsers. I
understand using `let` instead of `var` ensures each getter function has
its own binding for the KEY variable, but the same can be accomplished
(with less code) using a `.forEach` callback function, and this way
there's no need to worry about generating a unique name for the `key`
variable.
