You see, this is the kind of argument that I find very damaging to the
conversation. It lacks any shred of material evidence, evokes emotion,
manipulates the reader's opinion (framing them into
incompetent/inexperienced if they disagree), and implies an appeal to
authority. Please don't do that anymore.
Let me rephrase that in a proper way.
Functional style is very painful right now. Function you pass as
argument are executed implicitly, function as variable don't behave like
native ones, and with the new proposal, it add confusion on the function
returned.
It is kind of dumb that D do not promote functional style as it has
shown to solve many problems that arise right now.
The main issue is horrible garbage collector performance for many small
allocations. Syntactically we could do what scala does:
scala> def fun()=2
fun: ()Int
scala> fun : Int
res0: Int = 2
scala> fun : (()=>Int)
res1: () => Int = <function0>
