is it valid yaml? VSCode certainly doesn't think so. I think if you start the line with { you have to quote it, which is why we allow ${{moustaches}} at the line beginnings.

[jhheider]

I didn't try quoting it, but we don't appear to allow '$' for this key specifically (first example).

[mxcl]

aah well, certainly we should allow that.
