[web2py] how do I pass multiple variables in a Storage object to a function expecting named parameters?

[Carl]

I've got a request object coming to my Web2py app's controller function.

request.args[0] is another function name e.g., blastoff
request.vars are parameters e.g., Storage object: {'seconds':10, 'confirm' 
: 'okay'}

how can I call blastoff with the parameters such that I can write blastoff 
as...

def blastoff(seconds, confirm): ...
