Dubugging template rendering

[devope]

I have the same problem described here: https://stackoverflow.com/questions/24866030/mustache-php-debugging
Template waits a string, so accidentally passing an array causes a nightmare of debugging.

I am throw an exception inside of 'escape' to understand in which template file the problem occurs, but I still can't figure out which {{variable}} received an array.

Do we have some way to resolve this problem?
I scanned source code, but couldn't find any API for this.
