t-out automatically escaped content when it is a string not marked with the `markup` function t-out renders the raw content if it is a Block, or if it has been marked with the `markup` funtion. t-esc has been kept since it is safe and is optimized to render text nodes. all t-raw calls are in fact the same as t-out.
