prefer_new

X.new(...) in place of new X(...).

Flux. new X(...) is the constructor call, and it emits X.new(...). The lint fires when each part of the type path starts with a capital letter: Vector3.new(1, 2, 3), Net.Route.new(r), and HashMap.new<<string, number>>(). In an .alx file it also reads the markup: an attribute such as Size={UDim2.new(1, 0, 0, 24)}, and a {...} hole. A call that an ingot writes stays quiet. A lowercase name such as t.new() or self.new() may hold no class, so it stays quiet. X:new(), X.New(...), and a .new that nothing calls stay quiet too. The lint also stays quiet where new X does not build the same value: a call inside typeof(...), a call that a { ... } table follows, and an enum. So does a struct whose impl writes no new or writes New, and X.new() with no arguments inside the impl of X. alloy flux --fix writes new X over X.new and keeps the rest: X.new(a):m() becomes new X(a):m().

Set its level in the [lint] table of alloy.toml, or for one file with --@alloy-lint.
