The problem would be to get the 'index' in a simple, general way.
Python's error messages are not standardized. Anyway, starting
to parse Python's error messages to "improve" upon them in
MyHDL is obviously the wrong way (it goes completely against
MyHDL's minimalistic design philosophy).

The correct way in principle is equally obvious: use a technique
such that Python gives you a better error message. In fact,
thinking about it, complex user-defined strings are used
like templates, and a direct template approach may be much better.
There is a whole array of templating solutions available,
but the string.Template from the standard libary may be
just fine, albeit less powerful than format strings.
