Can't you use a template lambda alias argument to pushTo instead, so
then you can instantiate it inside pushTo?
.pushTo!(_ => _
I could do that. But I don't like it ;)
I don't think it's so bad, but fair enough
I can say the part I don't like is the _ => _ thing. Ugly. Other than
that, it's actually quite nice syntax-wise.
I'm also concerned that using a lambda is going to confuse or prevent
Why would you think that? If we can't trust the optimiser (dmd aside) to
inline a template lambda argument then phobos is totally screwed!
I admit this isn't a rational fear ;) I just have had experience with
lambdas where this does happen. The fear part of my brain is warning me,
but the memory part can't remember the specifics of when this happened...
What happens when you use a local variable in your lambda expression?
