The root cause of #1218 is that `invokePartial` creates a stack of data frames
for nested partial blocks, but `resolvePartial` always uses the value at top of
the stack without "popping" it. The result is an infinite recursive loop, as
references to `@partial-block` in the partial at the top of the stack resolve to
itself.
So, walk up the stack of data frames when evaluating. This is accomplished by
1) setting the `partial-block` property to `noop` after use and
2) using `_parent['partial-block']` if `partial-block` is `noop`
Fix#1218
If a decorator is used within a partial but not in the calling template, the hash is not passed in. For now error on the side of always including as just assigning values has minimal overhead.
Fixes#1089
Allows for partials to be defined within the current template to allow for localized code reuse as well as for conditional behavior within nested partials.
Fixes#1018
These allow for a given block to be wrapped in helper methods or metadata and allow for more control over the current container and method before the code is run.
This allows for failover for missing partials as well as limited templating ability through the `{{> @partial-block }}` partial special case.
Partial fix for #1018
There is no real need for us to do `.call(container` other than for backwards compatibility with legacy versions. Using the 4.x release as a chance to optimize this behavior.
