Can't use constant in python functions

[javierluraschi]

I would like to also assign constants with code similar to:

import hal9 as h9

h9.dropdown("dropdown", on_update=lambda value: h9.set("dropdown", value), values=['x','y','World','Universe'], value='y')

h9.html("html", rawhtml=lambda: 'Hello World')
