Use "with" syntax for nested elements

[dridk]

Did you seen the niceGUI project ? They use a very clever syntax to create the DOM syntax.

Instead of using this syntax :

html.div(
    html.h1("My Todo List"),
    html.ul(
        html.li("Design a cool new app"),
        html.li("Build it"),
        html.li("Share it with the world!"),
    )
)

why not using this one ! Easier to write and read

with html.div():
    html.h1("My Todo List")
    with html.ul():
        html.li("Design a cool new app")
        html.li("Built it")
        html.lit("Share it with the word!")

This was debated a little bit here: #916 (comment)

Technically you could create your own utility that implements this interface.
