Undefined used as weak map key #1319
Description
Hi,
I am using lodash with node.js 0.12.5 and am getting following error thrown.
return metaMap.get(func);
^
TypeError: Invalid value used as weak map key

On a first glance it seems strange to use other as a lookup key here as all non-lodash functions will cause it to evaluate to undefined (thus causing the error).
