pyright gives "Object of type ModuleType is not callable" with OO way for route about bottle

[defnull]

Decorators do not end with a colon. That's a syntax error. Remove the :.

That said: Bottle lacks proper support for pyright at the moment because it needs to support very old python versions, so you will get a lot of warnings even if everything is correct.

Sorry, it's a typo in my question, no colon in my code.
Regarding a thread on pyright issue tracker, seem it's a consequence of dynamic import at runtime (static checkers cannot deal with it... I forced py = (3, 11, 0) without improvement.

There is nothing special about Bottle.route(). It's a normal method of the Bottle class, the ModuleType is not callable error does not make sense in that context.

Hum, a quick look seems Bottle.route() return can be a module, because of load(callback), no?

Anyway, quick and very dirty fix, I commented, in Bottle.route()
# if isinstance(callback, basestring): callback = load(callback),
since I never use callbacks in route
static checkers cannot infer what is load() return type, function or module.

(not directly related, for those using static checkers, also add hints method: str | list[str] = 'GET' in route() signature, usefull when you need method=['options', 'post'] )
