The template documentation in Web: PLT Web Applications includes a little blurb about the in special form that wraps a for/list to make it easier to use. Are there other helper forms for other binding forms. In particular, are there any that wrap simple let or let-values? A real example from a template that generates Graphviz output: The following uses in and looks nice. It binds the values and generates the line for each query result. @in[(action-class-id action-class-label) (in-query `(action-class ,rule-id ?id ?label))]{ "@|rule-id|":"action-class" -> "@|action-class-id|" [style=dashed]; } But, since there should be exactly one result to that query and there is a lighter-weight function, query-values, that has more appropriate semantics - in particular, it will generate an error if there is not exactly one result, I'd rather use let-values than the sequencing form. @let-values[(((action-class-id action-class-label) (query-values `(action-class ,rule-id ?id ?label))))]{ @list{ "@|rule-id|":"action-class" -> "@|action-class-id|" [style=dashed]; }} works just fine, but is rather cumbersome. Is there a better way to write this using @ syntax? Doug
