Looks like normal code to me, syntax and semantics, not pragmatics.

Would this be considered valid in the Ruby world or is this just as

Did you write it? In that case, why did you write it in that way, or the
other way round
rewrite it differenly and compare.
In case you did not, no I do not think it looks crazy.

Now switching to the pragmatics you are worried about.

The reason I decided to try to make the aspect as a class even though it

If you are worried about your design because you do not like the resulting
code, I personally, and I might get strong opposition, think that you are o=
n
the path to perfection.
It is a long and winding road, and of course it is assympthotic :(

I can then register this class in my Aop engine which extracts the info

No of course it is not madness, but maybe you should rethink the design and
think about David's answer below (sorry if I messed up the posting position
).
