Hi ! >From those three I'd choose only <{ ... }>, it looks better for YAML while '%' sign looks foreign for YAML. Moreover, it needs extra spaces for writing expressions: Compare: 1. <%$.var + 1%> 2. <% $.var + 1 %> 3. <{$.var + 1}> One more point from me: We can't do things just beacuse it is familiar with N things and it should be so.
