Hm, are there no other ways in javascript to call a function by name? Eval is evil, it should be only used in some very rare scenarios. While promdash will probably mostly be used in a trusted environment, it would be great to find a different way.

Though, if there are no other ways, please make sure that the input gets whitelisted. Currently it's possible to define `{{label | alert}}` which will call the `alert()` function. It shouldn't be possible to use any other function than the ones defined/allowed. Who knows what javascript magic people can come up with to make that eval call evil ;)
