What are the steps to reproduce this issue?

1. Run Inspect Code against his file:

---@alias VArgs std__Packed<any>

local result = --[[---@type std__Packed<any> ]] {n = 0}
local result = --[[---@type VArgs ]] {n = 0}

What happens?

The cast on the last line appears to have no effect, and and error is shown

What were you expecting to happen?

The aliased type should behave the same as the original

The description for this issue was a bit off as the type cast was correctly occurring:

It was a bit more complicated, and to-do with the functionality that provides inspections on table literals being assigned to a shape type. Although, the alias was involved in the example above, it'd occur in other circumstances too.
