There was a problem hiding this comment.
I think this is a no from me.
ast.NodeVisitor has always inexplicably awful performance. I think @jgberry benchmarked a 20% overall increase in runtime over my original @singledispatch implementation, and the current custom dispatch implementation is another 10% to 15% better than that one.
Dispatching based on name is also just less clean than dispatching based on type.

Yep, see #42 for the performance related discussion. This was a decision we consciously made. Whether it was the right decision, perhaps that can be revisited. There are tradeoffs on either side. |

I see that now. I did some performance profiling too and found similar results.. |
