Allow function calls in {% if %} without returning *Value

[oal]

If I do something like {% if page.PublishTime.IsZero %}, I get a panic "function return type of 'page.PublishTime.IsZero' must be of type *Value."

It would be very convenient if at least regular functions that return a boolean could be used in if blocks. This doesn't just apply to time.Time, but also any other struct type passed into templates.

What do you think?

It's already on my TODO-list. See #9. :-) Will work on it.

Sorry, I didn't notice. I started writing this issue, then had to leave for a few hours. Didn't think about checking for new issues when I came back to finish/post it, but it turns out I wasn't the only one thinking about this today. :-)

No problem, yeah, was a coincidence. :-)

Should be fixed now with the latest 2 commits. Any types in function arguments and return values are allowed now. Can you confirm this works for you?

[oal]

Yes, perfect! :-) 👍

Great. :-)
