The previous protocol based tag type caused significant overhead
(in the magnitude of seconds). Removing this should simplify object
creation by removing typing.Generic from the __mro__
Profiling showed that WeakValueDictionary caused rather significant
and noticeable slowdowns during startup. Since the only thing it was
used for was to automatically remove the key from the mapping when
the reference count reaches zero, the same could theoretically be
accomplished by using the __del__ special method. There is a chance
that this could lead to a memory leak since the __del__ method is not
always called, but the only instances of this happening are during
interpreter shutdown to my knowledge and at that point the mapping
is the least of my concern.
This is a breaking change.
This does the following transformations, assuming `asset` represents
an asset type.
Object.is_asset_animated() => Object.asset.is_animated()
Object.asset => Object.asset.key
Object.asset_url => Object.asset_url
Object.asset_url_as => Object.asset.replace(...)
Since the asset type now requires a key (or hash, if you will),
Emoji had to be flattened similar to how Attachment was done since
these assets are keyed solely ID.
Emoji.url (Asset) => Emoji.url (str)
Emoji.url_as => removed
Emoji.url.read => Emoji.read
Emoji.url.save => Emoji.save
This transformation was also done to PartialEmoji.
