Maximum call stack size exceeded when template has values in it

[zapphyre]

When you try to assert on template that is having non-empty key-VALUES pairs, it ends with error:

RangeError: Maximum call stack size exceeded
    at templateKeys.forEach.key (node_modules/skorice/build/lib.js:41:24)
    at Array.forEach (<anonymous>)
    at objectWalker (node_modules/skorice/build/lib.js:41:16)
    at templateKeys.forEach.key (node_modules/skorice/build/lib.js:43:23)

    at templateKeys.forEach.key (node_modules/skorice/build/lib.js:43:23)
    at Array.forEach (<anonymous>)

I think, this will be the same as this issue ;)
