You can also do this:
require('simpletags')(function (html, head, title, body, h1) {
html(head(title('....')), body(h1('...'))
});
I'm using function argument names to both request data from the context and
assign it to variables at once in a control flow library I'm building.
https://github.com/bigeasy/cadence
Using the function argument names for key names, I maintain state for a control
flow in a hash table. If one of the functions needs a value, they name it in
their argument declaration list.
Notice on line 12. `stat` is the return value of call to `fs.stat` while `file`,
and `shift` are pulled from the context for use in that particular step of the
control flow.

It's a nice pattern. Works well.
It removes one level of annoyance. You don't need to assign each member of the
`simpletags` hash to a variable, but it isn't the full magic you're looking for,
where all of the variables magically appear.
