Literal "true" doesn't test as truthy

[arthurevans]

When I write an expression like it doesn't appear to test as truthy. {{ 1 }} and {{ !! true }} work as expected. Even if="{{ }}" appears to evaluate as truthy, but not true.

I think the issue is that true/false are treated as simple paths and not as expressions.
