can you give an example use case? I just want to make sure we're not creating duplicate functionality

Different file size per filetype, using line count for some file types,

I think there's some overlap with pattern, we need to make it clearer how they interact or maybe allow patttern to also be a function instead.

[kylo252]

how about this:

• if pattern is a function then the autocmd will apply to * instead, but the buffer will only be considered big if pattern returns true (maybe size should still be a fallback)

LGTM! 🚀
