Hi, I just saw this merged PR <https://github.com/JuliaLang/julia/pull/13412>.
In the past I used the functor trick of defining a type, and then a call method for the type, and passing this to a function, to get past the anonymous function inefficiency. Does this PR mean (to a mortal like me) that on 0.5 now this is no longer necessary? Thanks, Ben.
