## for some reason this failed because calling gets broken:

## if (args instanceof Array && {}.toString.call(kwargs) === '[object Object]' && arguments.length == 2)

## something above was not working, we do not need this anyways because this was a workaround

## to try to get `eval` to work, NodeJS is picky about `var` because of how modules are loaded,

## something without var is considered global, and becomes part of the context that eval will use.
