Ok, I dislike special prefix chars at all, in a language that doesn't have this concept elsewhere (despite strings of course, but their prefixes are just regular chars), Lists, tuples, and dictionaries are also introduced with non-letter characters.

I agree on the "#". Not so for lists, tuples and dicts. These are constructs in their own right, containing something, which is again made of normal Python objects.

But what we here have is an escape symbol, which expresses that the token following it is special and has special semantics, and the reach of this special symbol then even extends over its own line, but modifies how the next def statement is understood. This is remarkably different from being usual.

I should not have talked about prefix chars, but escape sequences, which fits much better.

As somebody already mentioned (Jim Fulton I think) this feels like mixing two different languages into each other.
