SVGMatrix still has a defined type even in a weakly-typed language,
doesn't it? I mean, if an instance can be used as (or cast as) 
as an SVGMatrix then it's OK. If it can't then it is an
error. Or am I missing something?

If I understand you correctly, then the methods are only defined
on the object when they are needed, right? In this case, it should
be fine, as long as the object can pass as an SVGMatrix.
