in operator not usable in if.

[AlexMax]

On the subject of if, the documentation says:

It behaves exactly as javascript's if behaves.

However, in converting some swig templates over, I found that they were failing whenever the template made use of the in operator. A failing test is contained in #659. Here is a backtrace for the failing test:

  Template render error: (unknown path)
    TypeError: runtime.contextOrFrameLookup(...).indexOf is not a function
      at Object.exports.prettifyError (src/lib.js:9:1149)
      at src/environment.js:9:23995
      at root [as rootRenderFunc] (eval at <anonymous> (src/environment.js:9:27$78), <anonymous>:19:3)

Pretty sure if in works fine with arrays, it just doesn't support objects. It should, though; thanks for the report and failing test!

Closed with merge of #661 - thanks @oyyd !
