Templates read {{if}} as helper without '#'

[s7726]

https://jsfiddle.net/tb58kjmx/2/

My data contains the key 'if', When attempting to expand the template I'm getting:
Uncaught TypeError: Cannot read property 'hash' of undefined handlebars.js:817
It appears handlebars is attempting to treat my template {{if}} like a helper.
From the way I read the documentation, to invoke the 'if' helper it should have the {{#if condition}} syntax.

This is unexpected behavior. Is there a suggested work around? Obviously I could mangle my data ahead of time, is there a way to escape the name in the template to get past the helper check?

If might work with {{[if]}} (#1251)
