Compiler error when 'using' is applied to a #soa pointer

Context

Operating System & Odin Version:

        Odin: dev-2022-09-nightly:74458ab0
        OS:   Windows 10 Professional (version: 21H1), build 19043.1889
        CPU:  Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz
        RAM:  32681 MiB

Expected Behavior

using statement would work fine on #soa pointers, just like on normal pointers and structs.

Current Behavior

When I try to use using on a #soa pointer, compiler shows an error. It seems like the compiler thinks the value is an immutable procedure parameter. Note that assigning a value directly without the using statement works fine.

Failure Information (for bugs)

In the example below, the compiler shows this error:
Cannot assign to 'b' which is from a 'using' procedure parameter

Steps to Reproduce

Here is a short example code which triggers the error:

Foo :: struct {
    a, b, c: f32,
}

main :: proc() {
    foos: #soa[32]Foo
    for i in 0..<len(foos) {
        updateFoo(&foos[i])
    }
}

updateFoo :: proc(foo: #soa^#soa[32]Foo) {
    // Working with foo directly is without any issues:
    foo.a = 123
    foo.b = 456
    using foo
    b = 1234 // Error: Cannot assign to 'b' which is from a 'using' procedure parameter
}

Also when using is applied directly to the procedure parameter, the compiler shows a different error - Cannot assign to 'b':

updateFoo :: proc(using foo: #soa^#soa[32]Foo) {
    foo.a = 123
    foo.b = 456
    b = 1234 // Error: Cannot assign to 'b'
}

I'm using just odin run to run this example.
