Re-export JsonTruthy

[Dosenpfand]

Or is there a specific reason why this is not done?

@Dosenpfand do you have a use-case for JsonTruthy? when implementing your own helper?

@sunng87, thanks for merging this!

Yes, exactly. I am using dotter which uses handlebars-rust with strict mode enabled.

Even with strict mode enabled it would still useful i my opinion, to have a non-strict version of the and and or helpers available. Would you accept a PR for that? Otherwise, I would try to get it merged into dotter itself.
