[Pythonmac-SIG] Keywords <=> Variables in appscript

[Adam Morris]

How can one refer to keywords  (the k) given a variable?

I'm working on a script that allows users to tell pages, for example,
to set the current selection's properties to stroke type: solid,
stroke width: 1.0. But I want to abstract all of this away. Coercion
is simple enough, but what to do about defined keywords when given a
string?
