Thank you very much, I'm definitely going to take this for a spin! Can I ask if you or someone you know uses this? I'm curious what the experience is like and if theres any downfalls.

A simple example:


func GetConfig(path string) mo.Result[*Config] {
return mo.Try(func (*Config, error) {
// logic to get the config
})
}

conf := GetConfig.OrElse(&DefaultConfig)

While it might not make much sense for a function you use just once, it can get actually pretty useful to simplify error handling like this for something you use more often.
