[filipesilva]

Fix #190

[filipesilva]

@mzgoddard @rowanoulton @ohze I'm not 100% sure this solves all the re-export problems but on the examples I tried it seemed fine. PTAL.

Any news on when this pull request can be merged?

[mzgoddard]

@filipesilva @Kamilius Sorry for the delay. This looks great. Thanks!

[mzgoddard]

@filipesilva I'm happy enough to see progress made for re-export problems as we find them.

any ideas? should I open a new issue? thx again

[mzgoddard]

@zanettin Yes please open a new issue.

[mzgoddard]

@zanettin I'll comment further on the new issue. If you can include any of the following info that'd be helpful:

• what loaders and plugins your project is using
• number of modules being built
• how big is the output js files normally?
• size of the output destination all together?
