Supporting this would reduce the need to get the type's name at runtime or force a type to become named.
I am logging this as a bug because this works without issue on other types such as int.

Expected Behavior

#caller_location should be able to take all fields of a procedure regardless of their type or if they are polymorphic

Current Behavior

Error
Error: '#caller_expression' expected a valid earlier parameter name
... roc($something: typeid, field:= #caller_expression(something)) {

Failure Information (for bugs)

When creating a procedure it is possible to get the value of a field for certain types. When the field is of a polymorphic typeid the #caller_expression is unable to acknowledge it as a field

Steps to Reproduce

1. create the following code

parapolyfield :: proc($something: typeid, field:= #caller_expression(something)) {

}
Color :: [4]f32
main :: proc() {
    parapolyfield(Color)
}```
2. attempt to compile the above code
3. Error 
Error: '#caller_expression' expected a valid earlier parameter name 
        ... roc($something: typeid, field:= #caller_expression(something)) {

### Failure Logs

just error during compilation
Error: '#caller_expression' expected a valid earlier parameter name 
        ... roc($something: typeid, field:= #caller_expression(something)) {
