Support "else X" for block helpers
In the JS library you can chain else with any block helper - not just if and unless.
I'm currently using else with a custom helper that does Regex matching:
{{#match cultureCode "^de\b"}}
...
{{else match cultureCode "^it\b"}}
...
This example can be worked around easily by changing the helper and switching to sub-expressions ({{#if (match ...)}}), but this is something that works in the JS library.
It would be nice if it allowed if, each and unless to be defined as regular helpers.
I created a solution for this (before I realised else if was supported) that expanded {{#A}}{{else B}}{{/A}} into {{#A}}{{else}}{{#B}}{{/B}}{{/A}}. Looking at the existing code it seems like combining the ConditionalBlockAccumulatorContext and BlockHelperAccumulatorContext would be a better approach.
The readme seems to showcase this as doable. What am I missing? See here:
{{StringEqualityBlockHelper @value 'dog'}}is a dog{{else}}is not a dog{{/StringEqualityBlockHelper}}
@sferencik Readme misses # before block helper call. Valid example:
{{#each this}}
The animal, {{@key}}, {{#StringEqualityBlockHelper @value 'dog'}}is a dog{{else}}is not a dog{{/StringEqualityBlockHelper}}.\r\n
{{/each}}
So you're saying it's an issue with the documentation (readme) but the feature exists?

It depends what feature you’re referring to. If you’re talking about behavior from Readme and your example - yes, it’s implemented. It you’re talking about the subject of the Github issue - no, it’s not implemented yet.
Oh, I get it. This is about a kind-of "else if" behaviour: {{else CONDITION}}.
