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.
fine grained reactivity:
existing key in source changes --> only observer having read the key are notified
add/delete key in source changes --> all source observers are notified
