It doesn't look like this works for -Infinity as requested in the bug. Otherwise looks good.

[fabiancook]

FYI to use -Infinity you will need to enclose it in a string

To get the Travis build passing, can you merge from master? We had a break when we merged the new transforms code yesterday.

[sandersn]

Never mind, if you can get it to pass without the merge, don't worry about it.

[fabiancook]

Looks like its good to go, tried a rebase off master and didn't resolve it, thought I would just try with Travis again, surprised it passes.

[sandersn]

Me too. But I'll go ahead and merge it. 👍

[fabiancook]

Hold up, is this not meant to be just const enum?

[fabiancook]

Ahh sorry, everything is good

Approved even for non-const enums.
