Idea for nicer syntax: Use handlebars subexpression

[MajorBreakfast]

In the talk Stefan (@iStefo) came up with the idea of doing something similar as is done in the link-to helper.

Example:

{{#link-to 'posts' (query-params direction="asc")}}Sort{{/link-to}}

I thought about it and there are at least two challenges:

• How to call it. Subexpressions aren't scoped in any way. I think calling it component clashes with the component helper
• How to specify the direction of each property. Mind, we can rename things, e.g. from -> outwards, but even with that it's hard to make it so that the syntax is easy to remember and when read aloud forms a somewhat grammatically correct sentence.
