Feature request: classname with radon hal -f

[mesinger]

Hey, thank you very much for your great work.

With radon hal -f, it would be nice to know which class a classmethod belongs to. Currently, if you have two classes with constructors in your module, radon hal -f prints __init__ twice, and you can't distinguish, which method belongs to which class.

Greetings.

Hello, sorry for the delay.

Currently I have very little time to work on radon, but this may actually be somewhat easy to accomplish. If in the meantime you want to open a PR, I'll happily review it.
