Suggestion: Option::take_if()

[Boscop]

Suggestion: Adding Option::take_if().
It takes a predicate (similar to filter, but for conditional .take()):

pub fn take_if<P>(&mut self, predicate: P) -> Option<T>
where
    P: FnOnce(&T) -> bool 
{
    match self {
        Some(x) if predicate(x) => self.take(),
        _ => None,
    }
}
