Every capture-free or static lambda has a built-in conversion to pointer-to-function. IIUC, the use of +
triggers conversion because the compiler looks for any intermediate built-in conversion that would allow +
on the converted-to type. Unary +
of a pointer is a no-op. And *+
is just getting a reference-to-function from pointer-to-function the way *
normally does.
