fixes#1548
- add a guard to show readable syntax error for if / unless helper
- prevents against 3 different errors that can be generated by different systax errors
* Added support for iterable object in {{#each}} helper
Currently {{#each}} helper supports either arrays, or objects,
however nowadays you can define custom iterable objects by overriding
a special method called Symbol.iterator, which results in empty result
being rendered.
* improved a test for iterables in {{#each}} returning empty result
* #each helper: using ES5 instead of generator functions in tests
* #each helper: using ES5 in the helper itself
- The "lookup" helper could also be used to run a remote code execution
by manipulating the template. The same check as for regular
path queries now also is done in the "lookup"-helper
Adds multiple variable support and the ability to set statement level logging semantics.
This breaks that logger API, cleaning up the manner in which enums are set, but the other behaviors are backwards compatible.
