Thank you Yichao.

For the record, here’s a modified example showing @inbounds working as expected.

struct MyType end

Base.checkbounds(A::MyType, i::Integer) = println("checking bounds ...")

function Base.getindex(A::MyType, i::Integer)
    @boundscheck checkbounds(A, i)
    return 17
end

function f(A::MyType)
    s = 0
    for i in 1:10
        s += A[i]
    end
    return s
end

function g(A::MyType)
    s = 0
    for i in 1:10
        @inbounds s += A[i]
    end
    return s
end

A = MyType()
f(A)    # performs bounds checking
g(A)   # does not perform bounds checking
