3.1.0 - Uncaught TypeError: s is not a function

[jonespi]

Seems like the new version is causing issues with some builds. I was able to workaround it by reverting to the last stable build 2.2.0, but seems to be a bigger issue.

I have the same problem (though with my own Map type). Maybe the merge function from deepmerge ignores the prototype and turns everything into a plain old Javascript object?

turns everything into a plain old Javascript object?

This is what the Javascript-Debuggger is telling me, that it's an Object (without functions), and not something of let's say Mutex or any other custom class I have.

From the deepmerge docs:

By default, deepmerge clones every property from almost every kind of object.

There is something in progress that will allow it to retain the prototype/class, but I don't know enough about the matter to know if it will be usable. TehShrike/deepmerge#208
