The most similar extant feature to this is compact, but it's not as compact
as this syntax.

$src = 'my.jpg';
$alt = 'My alt';
html::img(compact($src, $alt));

will accomplish the same thing since compact does the reverse of extract -
it pulls the specified variables from the local scope and puts them into an
associative array.
