Sometimes it is convenient to use
_ as a placehold for return values you do not care about. I wonder if there is any “danger” in something similar to:
f() = 1.0, 1, "foo" function g() a, _, _ = f() end
Here the variable
_ is assigned to twice with different types so it is not type stable. Will this be a performance problem even if I never use
_ later in the function?
