Implicit capture may capture more than you intended to. Explicit will cause the compiler to alert you to other names you might not have realized you included.

Implicit capture may capture more than you intended to. Explicit will cause the compiler to alert you to other names you might not have realized you included. It also makes it harder for people modifying your code to mess it up. That said, I usually use implicit because if I'm writing a lambda it's in a highly local context where a) it's just a shortcut, b) I know exactly what I'm doing, and c) it's not really meant for usability. If you want to make the intent really explicit and rigid, it might even be better to use a structured capturing type with an operator(): `MyCapture{.x = x, .y = y}()` or whatever.
