Though I'm not a fluent Python programmer, I don't know of any reason not to remove that automatic cast of not just string, but integer and object, to boolean, other than in the context where a true/false value is being sought (in a conditional expression).
Otherwise, FePy could find
someMethod(boolean)
before it finds
someMethod(object)
or
someMethod(integer)
as well as the
someMethod(string)
case mentioned here.
Perhaps ReflectedMethodBase.Call needs a new, optional, boolean parameter (default false) indicating whether an automatic cast to boolean should happen.
Another important question is whether there is a way to work around this in the current code. I'd guess that
WriteLine("%s", "string")
would work, but that sure looks like something you would not want to make into an idiom long-term.
